That's amazing, rank 30, that's really good! I think the Pokemon in the game will talk about your rank sometimes, and compare it to their own. Grovyle is very clever but I think their rank is right around there too!
The game is not monetized in any way (i think tipping would count) because I don't want to get in trouble. But if you want to donate, I have a ko-fi! That's incredibly generous of you but honestly, it's enough thanks just to know that someone out there is still enjoying this cool game i made 😀 congratulations on figuring out the secret behind the hearts and dots too, those things can be confusing on some of the puzzles
