Thanks, it will be cool. But unfortunately, now I don't have a possibility to make a mobile game(
In Godot you can just add some TouchScreenButton, bind them to the functions you already have for throwing the donuts, set them to “only display on mobile”, and generate a keystore using the keytool command, and include the .jks file into android export screen under Godot, and export as a Release build. You’ll also need to install adb.
Having a keystore set up and the game exported as release, you’re allowed to post the apk anywhere you want(even if you don’t have or don’t want to pay google developer license)
I don’t know about exporting for IOS
For some reason it has never failed me, every time I tried to export to android on Godot it worked like a charm. Maybe it’s related to some specific builds of Godot, or maybe something related to your android-dev environment?
Does it happen to you only in Godot, or also other game engines? Did you try Android Studio and it successfully builds/installs apks from your environment?
Did you setup ADB path, keystore files (for both release and debug), and jarsigner?
