I could see the potential of this prototype! Right now, indeed, the feedback really needs to be clear. First thing, I didn't really know if I should buy a new sword or not. I don't know what the other see, but the diamond long sword doesn't look different from the regular one. Second, the enemies getting hit isn't very clear. Maybe just a sound: "Tsh", and it could get 100x better! Good work! Can't wait for the next upgrade for this game!
