LAGS, dude. I'm blind af, and can't see your patreon. Do you even have it? Or how can i support you? Except buying your games, cause already did that, and i think that's too little of a support
Iirc, Itchio allows users to use the donation button by configuring payments.

Otherwise the other way is buying the game again.
