Really fun game, there is something really charming in this rolling guy bouncing on walls trying no to get killed by himself, spikes or monsters (Skulls are really hard!)
I really liked that the "R" just takes you back and doesn't reset the level; If you ever update the game I would love to see different types of bombs and blocks (You now like bombs that explode into smaller bombs or blocks that fall like sand) maybe even a shop to use the coins.
Anyway, really fun game!
