Love the silly vibe of the game. A+ title.
I think the player could use some more leeway for making mistakes before a game over. For example, hitting an obstacle could cause the player to be closer to the giant dice coming to crush them. If the player tripped enough times, then the dice would hit them, and then it would be a game over.
Oh, and I didn't understand what the "E" key was for. Maybe I never lived long enough to get to use it?
