This is pretty frantic gameplay! It's easy to grasp what's going on, although I never felt like I actually had any skill at it; I was constantly doing the puzzle equivalent of button mashing in a fighting game :-) Good fun, though; it was very clear what everything was, and the walls going "transparent" without disappearing and the bomb blasts having a similar sort of look was good, I thought. If this had have actually been a game on the 3310 I wouldn't have been a bit surprised.
