The game looks amazing! You've done a really good job on that.
On the other hand, there is this wall bug, where you can kinda do some wall jump. They don't really affect the game in any way, I couldn't exploit that (so good job on the levels!). Also the ending was a little dissapointing, when I fell through that hole, I thought I did something wrong and that hole was like in Getting Over It, but that was actually the end.
