Good game
A good concept, but for low-end computers, the fact that you cannot change the graphic Quality can hinder play experience. I myself, have beaten the whole game. For users stuck on 'Ricochet', here's the strategy:
Wait until the crate bounces off the first explosive, heading to the last one. Charge up the largest bomb you can, and send Boombot to the top-right side of the explosive. When the crate hits it, you'll be projected to the exit.
