Really beautiful art, wow, and very funny dialogue. I really liked both characters a lot, but Death (by weapon) was my favorite. The mechanics are really creative and unique, and the boss is a great challenge. The meteor style effects on the boss are really pretty looking, like something from a metroidvania boss, and the alternating between attacking and spawning minions is perfect, because you have to be careful of the minions, but you're also hoping for more because it's your only heal, lol. Very interesting way for those two interactions to occur (not wanting to fight enemies while low, but also hoping for more enemies to heal with).
I don't have a controller but I'm also impressed that you integrated controller support in your limited time. I can tell a lot of attention to detail went into this game, especially conceptually and artistically. It's only a shame that you ran out of time to finish the story, I wanna know what happens next, lol!
