I like the idea behind the game, and I don't even mind the difficulty--I just wish the jump button was separate from the arrow keys. I have carpel tunnel and I couldn't finish because my hand was cramping from being curled up over the arrow keys and having to click so often, up up left, up up left, up up down right.
Still, nice game. I talk about it a little more in my blog here: http://pajamagaming.blogspot.com/2017/01/free-itchio-games-4.html
