Mechanism: Finis
I've uploaded a final submission for Mechanism. Hopefully, it runs well for everyone who tries it. I got frame rates of 50-60 fps on two different Windows 7 machines and a MacBook Pro, but when I tried it on an older iBook G4 it slowed to a crawl (~10 fps).The game still could use a lot of work (texturing, lighting, sound, improved performance, etc). I'm planning to continue working on the game over the next few weeks/months, as there are many other features I'd like to add: lasers, conveyor beams, hunter robots, power-ups to collect, and lots of other types of devices...
I'm fried - I'm gonna go rest now. I look forward to playing everyone's games.
