I recently bought Balatro and discovered that the PC game can be converted into a Android APK through tools like balatro-mobile-maker and now I was wondering if this is the case for more games. Do you know any other games were something like this is possible?
Not exactly what you are looking for but there are tons of source ports:

Also there are quite a few Windows “emulators” for Android around. But IDK what the current hotness is right now. I havent kept up since the android hardware i own is too weak either way.
A few years back i grabbed a few fan ported Unity games on a discord server. But i dont remember the details sadly.
