It's pretty fun, though I have a few issues:
The lack of spin and momentum on the balls makes the physics a little unintuitive and the issues of how the spell card system works being rewarded MORE for your opponent scoring than them means you only score a little bit before the spellcards, which then becomes a game of "who doesn't die to this super chain?" because the supers do too much and the non-super cues don't feel like they do much more than help you a bit and your opponent a lot more. I really can't tell if I won barely all three times because of the supers or because of my own skill, because of how impactful the supers are, or if I just got lucky.
The characters aren't all that interesting and a bit flat, but it's not exactly the focus so I won't be too mean about it. The story itself feels weird because it both expects you to know the characters and acts like the characters haven't met before even though they have. (Note: by too much character, do you mean you had too many characters?)
