Not bad at all! Definitely the foundation for a really good roguelike! I love the idea of the player deciding the path and levels they take. Figuring out to right-click to rotate an item took me a while to figure out, and I'd like it if maybe putting items in the "use" slots would equip/be used immediately, as it was kinda frustrating to have to wait for my consumables to work. But yeah great job! Lots of fun. I've beaten 2 runs already :D
Oh, I would also love to see maybe letting the run go further. 2 floors felt really short.
