When it's fun? It's insanely fun man. Just mowing down row after row after row of enemies. And the art direction is some of the most impressive I've seen in a game. But my god it has this problem where the game gets so hard it moved past "challenging" and just went into bullshit territory. Not helped by the fact that a lot of the game's bosses have 2 (or even 3) stages and if you die you have to restart the whole thing.

Again the game is legit fun when it wants to be but at the same time I really would only recommend it to someone if they got in on sale (like me) or played it on easy difficulty.
