This was a lot of fun! I managed to finish the game and beat the boss. I loved the puzzle like nature of the whole thing. Also, the fact that you kept moving my cursor at the end of the game was a nice touch.
I think that the jumping mechanics could have been a little tighter. Trying to land on the top of the pointy trees with the current jumping method was difficult. This is a very small nitpick though. Everything was excellent!
