Im not sure if this is a controversial opinion or not but I don't think single player bomberman usually is good. At all. Usually its a slog and this game, despite Wario getting slapped on top of it, is no exception.

Sure theres a little bit of fun here and its a game that does get better as the game progresses thanks to some pretty fun upgrades (its really quite fun to shoulderbarge enemies into the path of bombs) but its mostly a pretty joyless affair as incredibly dumb AI enemies repeatedly bomb themselves before you tackle unfair and gimmicky bosses.

Multiplayer is where its at but because its the game boy, its still very limited even in the thing the series usually does well in. I'd rather play one of the others or the excellent power bomberman fangame than this any day.
