Cool little game! Presentation was very nice and clean.
The mouse movement can make the seem game broken, especially if you have your mouse on the screen when you start the game.
It proved be to hard to know what different switches would do, especially when some of them would just lead to the floor disappearing and leading you to a dead end. This lead to just jumping whenever I hit a switch to try to counteract it. Maybe have some feature that shows how the colors are going to appear so the player can plan better.
Having the timer be a full game reset is also harsh, since then it's just better to reset the room so you don't have to play through all the previous levels again to get where you were.
Some of the spikes are also pretty large, which made navigating down the 1x1 gap, would often just hit the first spike and had to be extra careful tapping left.
Pretty cool idea though!
