itch.io

If you go to this page on iPhone and click "Run Game" it should allow you to play. I tried it on Safari and OperaGX and it works on both. You can sort of keep the tab open to play in areas that you don't have internet access in. I hope itch makes an app that lets you cache and store games for mobile offline play. 

Brings me back to the days of having to sift through files from a crashed hard drive! Very cute!

do you have a version that works with Godot?
