The controls for the character are WAY too sensitive. I'd inch toward the tree or a rock and then the character wants to fly to the other side of the screen. Love the music, though. I'd probably make minebots available before being able to buy upgrades, but that's just me.
I can't even click the menus so god save those who did and said that they were awful. I can't figure out how to do anything outside move the screen around. This needs to seriously be fixed and redone... The idea has potential I'm sure, but I don't see it in its current state.
