Fits Theme: In the game we can switch the reality, when in one the platforms are a bit different than on the another. However, its not something that we doesnt see, but its something that doesnt exist untill we switch it.

Fun: Its kinda fun, however several things make this game hard to enjoy: 

1) switching cooldown - imo its completly not needed, or at least it should last for 1sec. 

2) slow - everything is too slow, accelerating game speed 1,5x can make this game more fun. Lucky this is dev build, so we can switch speed by typing "slomo 1.5" in console. However some levels are not prepared for that speed.

3) Wall jumping do not always register - seems like to make sure that walljump will register, we have to wait few hundred miliseconds after touching the wall. Sometimes it seems random, and its unpleasant.

4) It will me more fun when mechanics will be teached before the game will be require to master them.
