The fighting system is great! Ki techniques and transformation are hard to perform because of the small space, and you'll be easily attacked, and I like that! It makes it so they're not spammable. A few suggestions would be:
1. More modes: It feels kinda incomplete.
2. More characters: 16 is a lot, but it would be better to have more
3: Transformation selection: It would be cool if you could select which state someone is when you choose to fight with them
4. A bigger space: I know I said a small space makes ki attacks less spammable, but a bigger space would still be better
I can't think of anything else, and I'm suggesting these for the sequel. I understand why these features weren't added. By the way, when is it coming out?
