The idea is brilliant. At first I was a bit confused what is happening, but after getting the wallr rebound the game is much more "active" wrt. the gameplay. At first it would have been great to place more of the direction swappers, because making a tiny mistake would otherwise cause you to run across the map. What was very impressing is how "streamlined" the game is, in a sense that you clearly planned what the player will do in which order, which makes the exploration very rewarding. Good job!
