This was great Wes. I haven't played Hades but I love the idea of a game where you always feel like you are making progress, especially in jam games. Nice variety of upgrades and enemies, the game was fun to play and a good challenge. I also liked how you enemies visually telegraphed when they were about to shoot a projectile to give you a chance to get out of the way.
My feedback would be to have a death animation for the player, have some audio indicator for when you only have one heart and probably have less rooms before making it to the boss.
Overall, awesome job!
