Awesome work! The game is fun, nice variety of weapons, the art looks great, and the level up wheel of fortune is an amazing idea. I'd love to see the concept expanded somehow... perhaps tiers of buffs/debuffs that need to be balanced before you can spin? It feels like a really logical fit for a roguelike.
I got to the end of floor 2 and didn't seem to be able to go any further. I also had some freezes on pickups/damaging new enemies (on firefox if that helps?) Regardless, I had a great time!
