Just to let you know there is no way to download the game via the Itch app , it just pops up no compatible downloads. I know its happened a couple times with other Devs and they forgot to hit a setting or something on the back end.
Hi! Sorry for not answering before, I searched for info about this. It seems that this happens because I've not uploaded an apk version for the app. I'll look for info on the necessary things to have the apk using renpy and upload it as soon as possible.
