I really like this game. It's a very good idea with the spinning sword, and everything felt very intuitive.
At first, it was a bit confusing that enemies don't drop XP. I think it was an interesting idea that only the gold drops XP. However, I think it would be better if enemies dropped XP, but you had to obtain it by yourself. In this way, you are consistently forced to move toward a target to collect it.
Great game!
