The thing with the Mabel game is a bit complicated. There are actually two versions: the English version is just a demo, while the Spanish version is the full one, with about three times the content. Since it didn’t really take off, I decided to put it on hold and focus on this other game instead. I might do a remake or a sequel in the future.
As for supporting my work, first of all, thank you so much for even considering it. For now, the best place would be here on Itch.io, since it’s the one I check the most. I do have a Patreon, but it’s NOT active. I hope that answers your questions — Un saludo crack!
