Very interesting game and a pretty original concept. I like it a lot. I feel like the height from which the player can fall is too forgiving, making the game way too easy. There is a hidden-spike platform that feels pretty cheap : it is not difficult to avoid it, it's just impossible. It's punishment, not challenge.
Anyway, I like the art, the feel, the concept. I think this project has a lot of potential. I will be following it. This can be a very good mobile game.
