Awesome graphics and procedural dungeons! I did not survive very long at all in any of my attempts, most of the time Iw as attacked by 4-10 monsters in the first second. Maybe you could have the difficulty ramp up as the game progresses?

I'm not sure what happened, I was doing alright until I was completely surround with .5 seconds to reaction. Maybe set the player to invulnerable for a second after hit, and leave less health around?

Really nice graphics and proc. gen! The health of some of the enemies could definitely be shortened so it's less tedious spamming the attack. I'd love to see this as a full game!
