At first, I thought this game was misnamed, as you only have a magic bomb and a slashing sword, but after the first couple of enemies, you do get an actual shot. It's very clearly the same engine that this author used for his other game,
but adapted pretty decently. Terrain does limit you, and there's some interesting aspects like armor power-ups blocking certain kinds of shots. You die (explode!) rather oddly, and can keep firing (but can't move) while the rather long animation goes on. Supposedly, there's 9 total levels.
