It's a pretty simple game and I think it captures the idea of battling tops pretty well. I didn't really notice any glaring issues while playing as the quality of features seemed pretty well balanced. The shop had a lot going on but I felt like it wasn't too daunting to figure out. I did find myself unsure of who to battle as I didn't remember what weight my top had but that could be a design choice. As far as improvements, I think it would come down to adding juice and expanding the game with some kind of narrative, though not necessarily in dialogue form. I like the focus on action over text.
