I am a big fan of the retro game sounds, took me all the way back to early 80's games and arcade games.  Big nostalgia kick!  The boss was too difficult for me to figure out how to even damage him, but, this is way not my genre and I bet my gamer husband will be able to figure it out.  He loves games with good music so I'm going to have him take a look.  Do you have to hit the boss to a beat, like Crypt of the Necrodancer?  Because if so, that's even more fun. I'd love to see more bosses if you continue to develop it! (When the jam is over)

Boss was a little tough, I thought ducking behind would save me, but then the speakers did something and I died. Great music, i like the retro sound effects, it was fun chucking records at this guys head =D
