Nice work! Only issue I had is landing is very slidy and sometimes I would fall off the edge of platform. Guess that is the game though. Impressed it was made in SDL2 in such a short timescale :)

Good work

Great game! The graphics look nice, and the sound effects give the game a responsive feel! I like the variation in therms of enemies and the existence of those very dangerous debuff enemies. The game feels bloody difficult! Maybe 3 lives is too little? :P

Very cute and working quite good, I didn't understand how to use the power up as my slime fell instantly. Good game ^^

It is quite hard to control the slime and the "bonus" is really frustrating when you get it and die just after cleaning the room. I love the graphics though and the level design is good.

@stephen321 I love slippery movements, but I understand the annoying feeling.
SDL2 and C/C++ are not productive tools for making games, but I've gotten used to them.

@gamejmunk After the jam deadline, I found that a limited life count is not suitable for this hard game. I am going to make a post-jam version that does have infinite lives.

@rinkuji @solah I really like the poisoned chalice. Although this bonus was just poison yet.

@krit1k Thank you for playing this game.

I don't understand it completely, but the graphic's very cute, love the sparkles.

Good job. I go to the level 7 but it was difficult, mostly because the acceleration and velocity is low so its hard to be sharp in movement. Anyway, the idea is great and realisation is nice.

I really like the Art style !

I didn't quite understand the winning condition at first but it wall still fun and challenging even though the "punishing" bonus was not a fun surprise :p Good job on making a platformer in SDL too !

@caerul Sorry about that. I didn't have enough time to make a tutorial.

@junkai-chen Thank you.

@lepoulet I like slippery movements but I know that it is old fashioned.
Yeah, I am an 80's boy living in the 2020s.

@blk-dg Thank you for playing. SDL + OpenGL + C/C++ is an oldie but goodie.

Very nice, liked the graphics - was a little confused by what I assumed were supposed to be a power-up, as it just made me fall through the floor ^^'

But a nice throwback to games like Mario and Bubble Bobble.

Very nice garphs! and gamplay was really fun. Loved audio.

@smilfred As you can see it's actually a power-up.
It makes the slime large and invincible.
You can kill all enemies in that state, but you can also break blocks.
It will be used as a true power-up at level 40 and later, which will be made in the post-jam version.

A very nostalgic platform jump game, there is a little difficult. When I first started playing, I was very confused by the larger item.

Very nice and super polish, but really hard (after I'm not a plateformer player usually)

@01edward01 Thank you for playing this game.

@moonblast I am the one who made that item, but I was also confused at first about its identity.

@allosius To be honest, I can't beat at level 20 or later without dying.

Love the music for the ability- Goofy music as the game becomes absolutely chaotic. The game is very charming and I like the sliding, though I think the turning for it could be just a little quicker. Great fun nonetheless!

@cheville Thank you for playing. I can't skate, so I need some surrogate satisfaction.
That's why I love to make a game one can do ice sliding.

Lovely art and atmosphere, good work. :).

This was a cute game with nice art style, although pretty challenging early on! Overall a nice entry!

Pixel're nice.

YOU'RE INSANE HOW MANY LEVEL DID YOU MAKE??? Ok I managed to got to the 18th lvl but this game is waaaay to hard for me. But I'm bad at platformer so it's ok.

That's a super solid jam game you made! Good job!

I really enjoyed this game. Loved the graphics and music, and the game is a nice throwback to the classic Amiga games. It is a challenging, but keeps you coming back for more. Well done!

@eugenik @emmatw @chillertyp Thank you for playing.

@chocolat-endive Thank you. @linaju made 30 levels in 2 days. Not bad, right?

When I was a kid, the Amiga was so expensive that I didn't even dare to ask for it.
Going to a friend's house or arcade was the only way I could play the game.
Still, I have fond memories of having so much fun back then.
I was so moved that I am making something similar like this even now.

@chocolat-endive I wanted to make level 50, but I couldn't because I fell asleep.

Really fun game lots of levels gives my vibes of the old mario vs donkey kong on the ds great entry!

@aderpychickenstudiosoh I didn’t know that there had released a game called Mario vs Donkey Kong in 2004.
I didn't even know the sequel came out in 2006.
To me, Donkey Kong which was made in 1984 was the only one, but it's shocking that there are many others.
I was as shocked as I had been when I found out that my favorite game was called Donkey Kong and not Don King Kong.

I like the idea of a short level based platformer like this! It would be good with a bunch of levels and leaderboards. I did feel like the acceleration curve could be a little steeper but the challenge was nice!

Cute graphics! But I don't really know how to win, kill all the enemies?

The game is not so consistent with the theme "10 seconds", but I still enjoy it :D

@ggross When you kill all enemies, a portal that you can advance to the next level will be spawned at the top.

@joedev We've fixed already the player to be less slippery in the post-jam version.
However, we are hesitating to upload the post-jam version as uploading it might violate the rules of the event.

Very addictive and funny, I really like the sound effects, the graphics and the level design!

Cute and stylish! Really gives classic nintendo vibes

@bun @triangletriangle Thank you for playing and commenting.

Nice graphics and solid game play, good job!

Loved the graphics and I had a lot of fun! It was cool figuring out all the different interactions

This was a fun challenging platformer. The sprite work is very nicely done and looks nice against the backdrop. I love the sheer destruction if you grow big.

I wanted to mention though that there are some platforms that visually look like I shouldn't be able to hit from the bottom to hit enemies above. Like in level 8 (think it was 8), there are 3 heavier looking grey blocks as platforms. I wouldn't think visually something like that could be hit form underneath to attack the enemy above. Just a small quirk.

Overall this as a lovely game and well done.

I love this game, it's a nice challenge and I think the visuals and audio are super cute! I like the enemy variations, I think the ones with the bins on their heads are very funny and remind me of the Koopas in Mario :laughing:

I was a bit confused by the pink guys that shoot out of the cannons—functionally and visually, they act as power-ups, but they seem to cause basically instant death, so I assume they are bad guys?

I've played ten levels, and I really admire the dedication it must have taken to do so many level designs! Great work!

@rayriver @mcmuniz Thank you for playing and commenting.

Thank you for your thoughtful comment.
I totally agree with your opinion that that block seems immovable.
Actually, I made a similar comment to @linaju, but the Jam deadline was almost over and she couldn't fix it.

Thank you again.

@robeecodes What you feel about it being shoot from a cannon is exactly the same as our intention.
Actually, that Pink Guy is a power-up. However, on most levels, it just feels like a panelty as a result.
After level 40, it will be mostly used as a power-up.
The Jam version is made up to level 30, some of which can be considered that the Pink guy is pure power-ups.
For example, level 25 is exactly like that.

Thank you so much for playing and kindly commenting.

After nonconsecutive hours of blood, sweat and tears, I finally finished the game! 
Level 28 was a killer - I was ready to give up on that one, and I definitely spent over an hour on that level alone. Since there wasn't a tutorial, I spent many lives trying to figure out how to effectively use the slime powerup without breaking through all of the platform blocks. I know the dashed platform is the only one safe from breaking, but otherwise the best I could do was spam the jump button because sometimes the platforms wouldn't break. Is this related to the jump timing while you're a large slime?

I can't help but notice many parallels to this Mario Bros. Classic game and some other elements from the franchise (i.e. the enemy mechanics to koopas/hammer bros, attacking, pipe enemies): 

Luckily for me, I love Mario games! The slime powerup was unique, and I'd love to see more ways that the player can use this in levels.

I noticed a few features that seemed incomplete, but I suspect more will be implemented later - the '!' box in one of the earlier levels and the 1-ups that you get as a large slime. The game runs smoothly, and it seems very well made. Great job, and awesome level design!

@fuzzybut You genuinely moved me.
I couldn't ever expect anyone to finish the game up to level 30 before the end of the Ludum Dare 51 event.

As you expected, there are a lot of hidden features.
More moves for slimes like swimming and flying, as well as multiple item boxes and pipes that slime can move through it and enemies with different moves, have already been implemented, but they weren't included in the Jam version.

We started development with the plan to finish this game with around 160 levels, and LD51 only implemented 30 of them.

After taking a break for a few days after completing the Jam version, I resumed the development of this game today, and I was greatly encouraged by your comment.

Thank you very much for enjoying this game.

hard game！reminds me the old mario game on nes！nice work！

very nice game, lots of enemies and canons after the 10 seconds mark, lots of levels as well, sound design is very nice too, one of the best games i played during this jam, gg

@projectcolorball @enderswype Thank you for playing.

@benthetwoofus
I will try again today! see if I can finish the game

@projectcolorball I will be right here waiting for you.

@benthetwoofus i stopped at the level 23 which is too hard for me, here is some issue i have with it

I really enjoyed this. Felt like a nice mixture of games from the 70's-90's. The graphics and gameplay were extremely well polished for a game made in 72 hours. The audio was also really nice. I did find the "powerup" to be a little frustrating though, whenever I got it, I just fell through the stage. Other than that, this is a really great game.

@projectcolorball Thanks to a lot of feedback, we found that levels 23, 28, and 30 were quite difficult, and in the post-jam version we're making now, we've moved them after level 40. Thank you so much for playing hard.

@real-flamingicecubegames Thank you for playing and commenting.

There's nothing wrong with how you feel about the Power-up. A power-up that can even kill the player is exactly what we intended.

@benthetwoofus
you are welcome!

Very polished feeling platformer, and an impressive amount of levels! I thought the "powerup" was funny XD
