Way too easy. Most of the time it's easier to just try to get the guy straight to the exit (through "juggling" him with bomb blasts) than it is to follow the method the creator seemed to think you should take. Levels that I guess were supposed to be hard because they gave me 20 bombs would only take 2 blasts and they'd be finished.
Kind of fun, but I think I prefer
Asteroids of Orion for this type of gameplay.
