Okay, I wasn't convinced at first, but this is really fun. It definitely has a steep learning curve at the start, but once I got used to the control scheme, and memorizing which colors go where, and executing both platforming and watching the oncoming rooms at once, I can feel that this could be a fairly addicting arcade game.
It feels like the opportunity to score pairs is fairly inconsistent, since as far as I can tell the placement of rooms is random. It becomes a bigger problem once the secondary colors are introduced, as well. Maybe mixing in a room type that can take any color / a room that could take one of two colors would help?
My longest game so far (level 3) ended when I walked out a door to nowhere by mistake, and instead of bouncing me back like usual I got wedged between the invisible barrier and the room until that room migrated upward, at which point I fell out of the world.
