Cool game, the idea feels new and unique!
Unfortunately I havn't really had the possibility to use my computer much these last two weeks and the game doesn't work on the phone. I have been able to watch Yanni and Zach play though.
My main concern is that, at least on a small screen, the player blends a litte too well with the background. So Perhaps add more contrast between the player sprite and the background mountain.
But again, cool game! I look forward to testing it when I'm on my computer.
