Maxwell Rush

by lanz - 48 Hour Compo Entry

Hi all!
This is my first LD entry. Hope you'll have fun playing it!

Maxwell Rush is about being the Maxwell's demon. You have to sustain body temperature within acceptable limits using your force field to attract molecules and stop them from collisions with black walls(or to cause said collisions). Red walls are hot, they increase molecule's speed.

So basically in the top right corner you have thermometer with a black tick. When the tick reaches either end of the thermometer, game over. It goes to the left at a constant speed. Every bump of a molecule(blue ball) with any black wall pushes the tick a little to the right(the faster was molecule the greater the push). Bumping with a red wall doubles molecule speed. You can stop molecules with your body or push it in desired direction. Also press SPACE to pull molecules inside your forcefield (black circle) to you.
Press ESC to pause/unpause.
Blue bar in the top left will be getting smaller over time, so when it disappears you win!

It is written in C++ using awesome Qt4 framework and awesome Box2D engine.

To go to next level from the "Level completed" screen - click with the mouse.

Killer features:
-Become mighty ancient entity!
-Twiddle with physics!
-Programmer art!
-Over 4 levels!
-Over 0.5 sound effects!
-Secret level!
-Earn stuff!
-The only game where you can earn respect!

Thank you all for voting and kind comments! .) Special for you here are POST-release version. Rate main entry, then be free to play
It is ALOT easier, you can control demon with mouse("new-age modern"), also when you die, you restart at the level you died.

Fun idea and theme! Controls were a bit hairy, and i didn't get the goal of the game from the help screen immediately. +1 for using Qt :)

Cool and very different! Couldn't figure out at what speeds the balls started to accelerate out of control though...

Awesome game! "Heat is work and work is heat", check this youtube video about thermodynamics :P https://www.youtube.com/watch?v=VtEqn-5XHpU

Nice work on the physics part, the awards were pretty fun as well. The dynamics of the game are really cool!

Genius. I never thought of making that idea into a game. Physics nerds unite. Great game play.

Very unique. Really fun.

Very cool, a bit too hard from the get go...
Control's could be tweaked to use the mouse, I think (like the mouse acting as an attractor to the big attractor thing)...
Very original!

Very nice! The physics work well (only bugged out once) and the idea is great. Graphically it's a bit simple and there could have been more sounds. Overall, good work.

Nice game, very minimal ;)

Took me a second to understand what's going on. Now I have to say I really like to concept! I'd dare to say that maybe mouse control would make it easier.

Very original!! Found it quite difficult. Funny rewards :-)

heh, I really like the reward system - that was really cute.

Apr 30, 2013 @ 4:16pm

Had fun while playing it, the idea is definetely interesting :) You used QT really well, did not think it was capable of such things.

Fun game. You earned a comb with hair! Level 5 is brutal... didn't see that coming.

Once I got used to the controls, it was fun and interesting. I enjoyed it.

Really challenging, but having to restart from level one every time got a bit tiresome.

Never seen anything like it before. It's very fun. I didn't catch initially that space controls the forcefield - that made it a lot easier! Still a good difficulty though, I think.

Loved the awards. Controls are a bit hard but overall fun.

Quite clever! Love the physics of the thing, pretty cool!

Interesting game, but It felt like nothing I did had any effect. I read through the instructions a few times, but I was still left quite confused.

Fun idea, Fun game. Altough it seemed a little hard for me at times.

Thank you all!
If you find it too hard, fell free to play post-compo version with mouse control.
Have fun!

May 9, 2013 @ 9:43pm

This is hard :)
Also very cool!
The end-level prizes are truly excellent.

So my friend told me he wants me to make a game about Maxwell's demon and I said that I didn't think it'd work... Five in innovation and yay for physics! <3

And woohoo! I got re$spect.

The physics worked great (I should try Box2D in Python) though you can exploit them in level 4. Push a ball to a corner and hold it. Release to increase the temperature and hold it again. Finally, you should make MB1 attract in the post-compo version, and WASD still moves the demon.

Fantastic work!

PORTS: Ports to other platforms can be done after the deadline. That said, the sooner you finish your port, the sooner people can play your game, improving your chances of placing in the final results. For best results, provide a Web version of your game, or a Windows version with no dependencies. Also be sure to rate about 20 games to improve your visibility.

MY GAME DOESN’T SHOW UP: If you can’t find your game, it’s usually because the URL to your downloads are missing ‘http://‘. Fix your URLs (http://mysite.com/mygame.zip) and you will show up.

MY GAME CRASHES, IS UNBEATABLE, OR I MADE A TYPO: We allow you to fix crash or win condition bugs after the deadline (in a sense, like “porting” to support more players). We also allow “typo” bugs. I.e. A true that should have been a false, a word that should have been a different word, very tiny changes that you would have caught if you had more sleep. We leave this open to interpretation, but generally speaking your game should be identical to the game you submitted. No new features, just things you messed up last minute. Typos.
