When I download the mobile version so i don't gotta pay for it cause i am pc. It just says "save as, save" and I'll do all that and it won't open it just does the same thing over and over
The mobile version won't open on PC unless you run it through a mobile emulator. Bluestacks is a popular one for android emulation, I don't use them but it's an option if that's what you're after.
Worth noting the paid version on itch.io for PC is unsupported, and you can get the game elsewhere in a properly-working version. Still costs money, but comes without some ad spam you get on mobile, and also with a few extra cosmetics which you'd have to pay for in the mobile version.
