This is awesome! It reminds me a lot of Baba Is You, which is good.
The concept is implemented wonderfully, and the level design is very nice. I would
buy this game if it had more levels.
My only 3 gripes with it are:
1. The sound effects are not that good. Like the death one sounds very weird.
2. There is no undo button. I believe this would add to the game. If you die, and know you're on the correct path, It gets annoying repeating the same movements over and over again...
3. There seem to be difficult spikes.
Other than those three, This is an awesome game. Well done.
