The game is too frustating or is just needs too much precision, you should remove 2 spikes (the spikes you made are 1 block long, so maybe you could remove two or one) here and there to make it more easier. I only got to the dashing ability and I was stuck in the level where you need 2 keys to open door and that has a spike pit. But overall the the game has a pretty good feeling, It seems that the story will be deep, and has cute simple graphics. 7/10
