Love the idea of the game, It's less like a platformer than it is a puzzle game because you have to use the idea of no gravity to solve a portal style room. I 'solved' the first one by just running of the starting platform and floating to the next. Really well done.

Thanks for playing. Yes, the first room is intended to be solvable simply by running off the platform. It introduces the concept of there being no gravity when you leave the metal floor area, instead of being able jumping around on platforms. (The first room is actually specially coded for this solution, because normally you don't auto-attach to metal floors if you're moving parallel to them.)
