Great aesthetics!
I liked how you take weapons from enemies, but I think it requires more balancing, i.e. you don't want to damage their gear, because you might need it later. It would also be nice if instead of "slot1" etc., it right away showed names of weapons. "Slot1" sounds more like an empty slot. Maybe you could leave it below the slot, if you want to highlight the numbers, but put the weapon name inside?
Overal - nice game, but unfortunately it froze after the second battle, so I'm not sure what would happen next :(
