This is probably my favorite shoot 'em up I've ever played. Unlike most other games of the genre, the difficulty isn't super hard, it's actually perfect to me. I also love the weapon system for this game for it being simple, each weapon is useful in some way, and they're just fun to use. The story is goofy fun and the graphics/aesthetic/music of the game reflect that well. The only problem is that it was stuck in Japan, but that's not the game's fault. It's just a fun game.
