Mighty Magnetic Force by pvwradtke

[raw]
made by pvwradtke for LD32 (COMPO)
After a work accident, you become a blue/red ball that generates a very strong magnetic field. On top of that, you've been transported to a world with enemies that can destroy you easily. All normal on a scientist's day.

Manipulate magnetic forces (red and blue) around you, and use them to destroy all enemies around you. You can move one way and manipulate the madnetic field independently using the controls.

- Gamepad (best, use it. I mean it!):
Left stick to move
Right stick to rotate the magnetic field (you point the direction the red field will be)

- Keyboard:
Cursor keys or WASD to move around
Mouse cursor to point the direction the magnetic field (red) will point to.

Good luck and enjoy.

Works on:
- Linux Mint and ubuntu
(you can compile it for your Linux flavor, depends on SDL2, SDL2 image, SDL2 mixer and SDL2 ttf)
- Windows

Not officially supported, but this should compile on a MacOS X without a problem. I just don't have one to do it.

What I used to do this game:

- C/C++
- SDL2 + Chien2D (my open source game library)
- Code::Blocks + gcc
- Gimp
- Audacity
- Tiled
- Bfxr
- Ogg tools
- Linux Mint
- Mingw32 (cross-compile to Windows)
- Punk-O-Matic

edit: added support to WASD /(silly of me to forget it! :D). Still under the submission hour, that was pretty fast :).

edit2: added info about what I used to make the game.

WOAH. Very nice gameplay! Once again, you did it! :D

But the song... is... a bit too loud @_@

Thanks Foxtacy. Owing to the amount of work on other parts of the game, there was not much time to better engineer audio ;). I'll look into it in a post-compo version :).

Really cool mechanics, I played it with my gamepad as recommended. The learning curve was solid as well. Overall a great challenging game!

That was brilliant. There are a lot of "magnet weapon" entries but this one stood out. I think it just the hundreds of small design decisions. From the level design to the way boxes are launched rather then pushed.
And a hundred other small things I cant put a finger on, but that must be there because the game was just that fun!

Anyways, I think this entry deserves to win.

Cool concept! I found it a little hard to control and actually hit enemies though. Nice take on the theme though.

Great gameplay and mechanics. I really like this magnetic idea.
I have to agree that the music is a little too loud and gets old fast but beyond that it's a clever action / puzzle game. Good Job!

Control was great, I wish there was a bit more analog ramp-up with magnetic repulsion when you get closer. As you get closer it's nothing nothing nothing SHOOT ACROSS THE ROOM!

I liked attracting the square to me, then slamming the right stick in the opposite direction to shoot it, felt very Magneto-ish.

Really cool take on the theme. Controller support was a nice touch, too.

Very good music in this game, and an interesting mechanic too.

Loved it. It needs work but I loved the idea and execution so far.

I had fun playing this game, it was way longer than I expected I had to go at like level 10. But it will probably be a game I come back to. Music doesn't fit the mood but I like rock so I guess it works out. I got the hang of the mechanics(good level progression) and started dominating, which is always felt nice. I'm sure the later levels will be hard.

It's my 6th attempt to download the Windows zipped file now. I want to play this but I can't seem to finish downloading whole files.

Sorry to hear that. I tried it now on my cell phone and I could download it correctly. I'll try to provide an alternate link later tonight.

Great game nice the magnet mechanic although it would be nice if there was a reason for the different colored squares. Also, if a square isn't moving it doesn't kill the enemies and I managed to catapult the blue square out of the last level. Overall a fun game to play.

Thanks for the bug report, seems like the collision code could see some improvement. As for the different colors, the idea was to play with the opposite magnetic forces, but I didn't had the time to properly work on that for the compo.

Finally, as for the squares not killing the enemies while idle, that's the same as with bullets, they only kill when shot, so it felt like a natural decision. But it's good feedback, nevertheless, as it should be more clear through the tutorial.

Fantastic game! Using magnets to push or attract things is genius and a good use of the theme. Audio is great, well done!

I really liked your title screen. I'm glad I had a gamepad on hand, it made playing it much easier.

Impressive soundtrack for 48 hours. The physics are a bit wonk, but I had a lot of fun playing it and beat the whole thing. Don't remember what my score is because I don't think I saw it on the credits.

Good concept, use of the theme, and puzzles. Stage 10 was very challenging. It'd be interesting to see more puzzles that expand on these concepts--for example, enemies that could only be killed by a certain color.

@dylanwolf: thanks so much for the comments, I guess that your idea helps expands why we have different colored magnets and can really improve the game and make it a bit more challenging on later levels. :D

Great gameplay, art, and audio. Only things I'd mention is the music is loud and there is some major input lag where the game has to catch up sometimes.

Hi Tortoise, thanks for the feedback. As for the input issues, were you using which version, Windows or Linux? Were you playing with the mouse/keyboard combo, or with a gamepad? If a gamepad, which one was it? The game barely uses 5% pf the CPU on an old Core2Duo processor, so it'd be interesting to know more about the issue.

Very fun and kinda hard, I lite it!
Mine is also about magnetic force, check it out XD

Hey, I'm Rodrigo Oliveira, from IGDA Curitiba ;)

Nice set of puzzles, had to think a lot on some levels :p

Sometimes the red rectangle didn't collide with the enemies. Also, one time the blue didn't collide with the wall, travelling to outside from the map.

The music is amazing too!
