Thanks for playing! I agree that some of the weapon balance is off, I've fixed that in a version that I'll release after the jam is done. The dungeons aren't currently auto generated, but I've been thinking of implementing that for a while, probably using the same system spelunky does to generate them. I think bosses would be really fun, but I need to do a major update to the enemy system to implement them!
Either way, I'm glad you enjoyed, be sure to leave a rating!
