B_T, thanks for the screenshot comparisons. Good stuff.
Panic Bomber, unfortunately, is not a particularly engrossing game. Perhaps it does better as a multiplayer... but it can't hold a candle to the likes of Puyo Puyo (also available on PCE).
I don't know, maybe I'll give Panic Bomber another whirl soon, just to see if there is anything to get excited about. I think I can get at least a 3-4 person game going, so we'll see if that has potential.
