That's a really fun game. I had to restart it for it to work properly as it didn't seem to be able to earn points properly at first. I was making a point for every 6 or 7 enemies, but a reset player stats and game reset fixed it.
Made it to Wave 42 on my third run.
Not entirely sure what Yeet Force is. I am guessing it's the power with which the balls are launched.
I just noticed your message about the points system being broken. Hopefully my fix works for everyone.
