Great game. It feels really polished and you guys definitely know what you were doing!
I only ever banned goblin modes and maybe a few weapons. I also only walked backwards and shot at the goblins; I think having something to walk towards like health/xp pick-ups would be a great way to guide the player where to go and make them look forwards from time to time. A "berserk mode" or something where you become invincible or get a big Aoe melee attack would also be a great way to make the player walk towards, instead of away of the goblins.
Presentation is top notch, originality is top notch, it is pretty fun and you definitely have mode in your game: Congrats!
