Wow, this is a really crazy submission, there's a lot of really cool ideas here but man did the scope creep get the better of you. Honestly though still a great submission, but one thing, ALWAYS ALWAYS ALWAYS.. ADD SOUND!even if they're super basic sounds! You can just use jsfxr to generate sounds in easily under 20 minutes, and sticking them in is also pretty quick if you've got a standard game engine.
