I've probably found my favourite game so far. I love the humour, the artwork is great, the music fits wonderfully.
The only thing I didn't like was the fact that Rin's sprite hid bullets, and the hitbox is not near the center of the sprite; so many hits because it's so much further down than I expect or just not seeing the bullet.
(Also had some frame issues, but that's probably because too many corpses produce too many bullets and I'm playing it in browser)
