This was a lot of fun. The character is cute and I liked how the color changed between rounds.
Once I realized that I kept my number of spins and stat cap even if I died, I started using more of my spins to increase those two things early on. It became easy to become OP that way, because I didn't feel bad losing a round while I was increasing those things. While playing OP can be fun sometimes, it might be nice if the game was a little more balanced.
It would have been nice if the cursor was a little clearer. I sometimes had troubles following it as I moved around.
At around Round 14 (I could be off by 1 or 2) my character moved up to the top of the screen on their own, and I could not make them move down. I could still move left and right. I played to Round 17, then lost and hit play to see if that would fix it. My character still moved up and stayed at the top of the screen. I had been playing in full screen and exited out of it, then pulled full screen back up, and that's when I noticed the issue. I tried playing out of full screen, but I still had the issue. I refreshed the game page and that seemed to fix the problem. I pulled it back up into full screen, played a little, then exited fulled screen during the combat. When I went back into full screen, my character moved to the right on their own and stayed there. This time I was at Round 2, so I think the issue is not round based.
