its a pretty solid submission, i think the last 3 battles need some balancing since it feels like you need to make a specific build in order to beat them rather than letting the player get creative and make their own build. the second last one felt borderline impossible but that could be a skill issue on my part lmao i love the concept of upgrading your own bayblade parts. the game could use some visual polish but other than that good work! :^)
