Is there a way to repair items? That would be amazing. Also, when you quit and then continue your game your weapon uses and your artifacts reset.
I feel like restoring item uses would be more appropriate at the end of the floor. Maybe they shouldn't even be gone forever when you reach 0 uses, but just broken until you reach the end of the floor. Right now, you always feel it's more worthwhile to spend money on artifacts than weapons, so re-chargeable weapons sounds like they'd be more worth the gold
