itch.io

So I just fixed it, I downloaded an app on the play store called apk-signer, I signed the apk file, then it installed without a problem and it plays just fine! Thank you for your quick response though.

This is definitely shame on me since I didn't try the free version first... but I'm trying to install on android, I have the file fully downloaded, it installs about 80% then says "could not install". Any help would be appreciated.
