I did one run with each character, went to room 13 with the priest the best (running around the borders of the rooms works until it doesn't ;)), with 137330 total damage. I specially like that the 3 weapons are quite different with even a few dedicated upgrades as well (like the notes bouncing).
The game is fun. The speed of the character and bullets feel right, the game is just hard enough, they're not 100000 different enemies but the various enemies including the different bosses are different and all fun to deal with.
It's actually the thing I struggle the most with myself but I think the projectile from the priest should make some loud noise, it can feel satisfying with that sort of bomb, low rate projectile.
That's a cool entry, thanks for sharing.
