This sure is "one of those" and yeah, it's fine. Not offensively bad, does what these games do but doesn't do any of it in a particularly interesting or banner way. Played 2 and a half hours of it and think I'm done. Thought I could play the bullethell-arena-roguelike genre or whatever the hell you want to call it forever but this squashed that thought. Best thing I can say about it is that I really liked the music. I don't think it fits the vibe of the game but it did make me very nostalgic for gameboy music in a way that most other chiptune stuff doesn't.
