My god does this game rock. 7 (+1) playable characters with 2 modes and each plays like a shmup of it's own. each level and boss feels varied as hell. it really hit me when i was playing Tetris against a mid boss on one of the stages. it has bullet grazing too and it's not just a score thing since your bullets get faster and stronger when grazing. personally not too fond of 3d visuals on shmups but that's basically a nitpick for such a game.
if youre deep into touhou and cave, looking for a middle ground. or just wanna play an actually good shmup play this game NOW.
