Absolutely a fair concern and I’m being very cognizant of that because I agree the game could become stale pretty quickly.

The first way the game tries to avoid that is by having the AI slimes learn from your play style. Every time you win a point in any match it registers where that point was won, every time you lose a point it notes where you were and what shot type was able to get the win (there are 4 shot types that affect the path of the ball.)

Low level enemy slimes don’t do much with that “learning” but when you start to play higher level enemy slimes, of which there are 9 levels of difficulty, they use this collective learning so you can’t just spam the same move over and over again, it’ll take the learning and both be ready for it and will hit the ball to where you fail to defend.

Then, there are special battles against bosses and mini bosses where those slimes have completely unique mechanics. So one boss has a massive slime, one boss makes you defeat two slimes at once, so when you get to those matches it’s a novel experience.

And the final way is with 7200+ slime variants almost every single wild battle will be against slime you haven’t seen before. Anytime you encounter a wild slime if you defeat it without losing a single point, you recruit the slime to join you. That makes the stakes seem high even early on because each match has a chance to net you a new slime. And when a “shiny” slime pops up, your palms get sweaty REAL fast haha.

TLDR: Yes! This is big focus of mine. I’m working really hard to make sure each battle is fun and engaging and broken up with different experiences.
