Intersting and fun game. When you know how to control and color balls - it is very rewarding.

It's a very fun game! Good job, the gravity gun/wepon thing is a really cool idea, the game could use some music or SFX though

It's a pretty interesting mechanic, and the physics work pretty well. It'd be nice if it told me I could double jump, got stuck on that for a bit.

Good game!

The platforming was hard and I love the idea of moving the balls with gravity! Took a second to understand to mix the balls to open the gate.

Good use of the theme!

Awesome job!

Cool mechanic. Really hard to jump and walk on platforms though. Didn't play the whole thing but i think you could make som nice puzzles with that gravity gun.

This is a fun game ! It's nice to have a smooth gameplay ;)

Nice job for your first LD! Could have used some music and sounds, but other than that, solid for your first game. :)

This was fun to play, simple yet very engaging mechanics, good job!

Had issues for some reason with the game running slowly at times but when it ran at normal speed I did like the gravity mechanic.

Interesting game.
(Google Translate, I'm French)

Awsome menu i liked the how the controll felt you could of spent more time at graphics but its grat anyway.

this is really cool ! controls could be nicer but still very playable

Neat! It gets easier once you get the hang of dragging a whole cluster of balls with you. I think I finished it (smiley). Nice touch with the advancing wall of doom :)

Interesting idea. Once you get the hang of controlling the orbs, it's quite fun.

Liked the gravity mechanic, but didn't like trial and error method for knowing what color of key is for what color of door (probably, they should simply match). Also the animation for field is horrible:-)

Definitely an interesting concept, and quite fun to play. Your artistic sensibilities are a bit weird, but I'm willing to look past that.

Some notes:
Bug report: So what happened to me is that I died to a red line over lava, was respawned at the yellow save point, but the puzzle didn't reset - I was stuck behind the red line and could not progress.

The fact that you can bring your previously color-shifted balls with you kind of breaks a lot of the puzzles. I don't need to maneuver a ball to the green-erator if I already have a green ball, after all.

Also, as a pet peeve of mine: if your only keys are for the four directions, please please please use the arrow keys for that! My ASDW keys are not in the same place as yours, and it's a real hassle to change keyboard layouts just to play your game.

Anyway good job!

@stoarch @w1n5t0n @minnouu @AlfalfaStudios @Vulkanmannen @marccspro @manabreak @MJaawa @Mimus @ddalacu @texdata @Andrew Quartermain Thank you very much!

@plams Yep, that's the end :) And thank you very much!

@Franklin's Ghost Yeah i was afraid of that, there might be some performance issues. It's not a well optimized game, sry about that.

@scorched yeah, i guess i could make it a bit more clear, i hope it wasn't too irritating

@cgmorton First of all thank you much for such detailed feedback.

Art - well i don't have any experience with pixel art and i didn't have much time to work on better graphics, sry about that i will definitely improve my art skill for next games.

Bug report: yep, i am aware about not reseting wall position, i will fix that soon. Until then you can run into wall to reset it's position (and you will also respawn at the checkpoint)
About bringing balls (hehehe), that is also something what i should take care of and i will try to fix it (no promises on that one though).
Keyboard thing: sry about that, i wasn't really thinking that it could be so annoying. In future i will give option to play with arrows or WSAD.

I want to thank you all for taking your time to play my game and give me feedback. You guys rock.
It's my first LD and i didn't expect it to be so fun and exciting.

10/10 nice work m8 keep it real

Main menu was cool, but when I got in game, it seemed jerky and like it was freezing, even though my computer was powerful. Very strange, since it showed the menu fine, so it wasn't java.

No rating given :/

Very fun. Controlling the balls and managing your player can be a bit tricky at times but the concept is very cool!

Graphics and audio obviously could do with some sprucing up as you've pointed out, no prizes there, but all in all a solid game. Look in to focussing more on these two areas for your next jam and you could have great game on your hands :)

Cool game play and an interesting puzzle aspect.

It does not run for me. Gives a generic "unable to run" message.

OS X 10.10.2

@nivalis thx m8

@Mixer hmmm, maybe try closing browser and other processes. Sometimes it does run slowsly for me when i have open Chrome with 10+ pages. Anyway it's my fault for not optimizing game, sry about that.

@Frewz @bentfglasstube Thanks!

@Incredible Ape I wasn't able to check if it's working for OS X i added OS X version because it should work in theory but apparently it doesn't. Sry i already removed link for OS X version.

I can't run the game :(

Good use of weapon.
Plays well.
Well done on your first Ludum Dare.

Interesting concept and a solid entry, some jumps are hard to make but thats all there is to it.

Interessting mechanic. Good game.

I really liked the feel of controlling the orbs with gravity. Combining that with platforming makes for a cool package. I ended up getting stuck behind a lava wall due to a checkpoint bug, but I thoroughly enjoyed what I played. Great work!

Pretty interesting mechanic. The physics work pretty well. It's your first LD! Thumps up!

I could just try the Demo.jar (that seems to be the concept), but the GravityGram.jar hangs on my computer when I first see the character. It freezes.
I would have pleased to try your game.

I did have some serious frame rate issues. There were long pauses between frame updates and I was on a powerful computer. However, I did find the frame rate improved when I closed many programs running on my computer. (I'm guessing there's a problem with the delta timer or something.)
Now that I have played the game, it was pretty good. Managed to get to the end with the smile. :)
I did have some problems clicking as it usually take two clicks to shoot another orb when one is already shot. I'm not sure if I have to right click to delete and THEN left click to shoot.
Nice work, but I hope you can find the issue to that frame rate hiccup. Just to let you know, I've also tried the demo and there was no frame rate issues with that.

@Pixel Heart Could you describe what happpens exactly?

@asobi tech @TeamCalcium @Junber @TheMeorch Geckoo1337 Thank you very much

@TeamSpatch Hmm, so game freezes in main menu? When you mouse over one of options? Thanks for feedback i will look into that.

@jprogman Thank you for such detailed feedback, and all your effort for trying to play the game. I am aware of performance issues, the easiest way to solve that is to make smaller levels and not loading whole map at the same time. About clicking problem; i didn't know about that and usually it works fine for me but i will try to deal with this bug as well. Thank you very much again for your help :)

Original mechanics, but very unforgiving IMO. Overall the game feels right, I love the physics, and the character is not frustrating to control (very important for that kind of platformer).
Even if they are not part of the gameplay, the menu animations are cool too.

Of course it could use some audio and graphics for it to feel more lively, but the mechanics are definitely there. Good job !

Very interesting design. And fun. The physic of the orbs seems fine to me. You should clearly go further. Congrats !!

Hi, cool idea! No Azerty controls though :(. Also, it's strange that the ball doesn't keep it's previous velocity when you dispel the gravity field, and just falls straight down :p. Once I adjusted I was able to move forward though. Controls were a bit too sensitive for my taste, making some platforming sessions quite frustrating, but other than that, I mostly had fun.

nice game! i liked the idea. it was a bit hard to move around (i personally would like "w" for jump) but nice and neat

Cool game, but crashes with nullpointer exception when spamming the shooting button.
Have fun testing our game ;).

Decently fun game. I've been wanting to play around with gravity mechanics like you in my own games, so nice to see it in action.

The platform mechanics themselves feel a bit...I don't know, somehow too fast and too floaty. Going with one or the other would probably serve the game well.

Awesome game, nice job with level design. The player animations made the game feel really smooth. Could have used some sound effects. Graphics were sufficient, although I would have liked to see perhaps a better animation for the gravity field. Overall well done, high five for java/eclipse!

Simple but still pretty cool entry. I really lika that gameplay mechanics!

Our game mechanics are similar, indeed =)
Very well done, but I had a few problems running it, it would run very slowly. The Demo.jar was ok though.
