itch.io

When there is a new update for the full version do they have to pay for it again or they don't need to they already have the full version

I have a question if someone buys the full version and there's future updates for it do they have to pay extra or have to pay for it again or does it automatically become free for updates if you already paid for it

Is there going to be future updates or is it already fully finished

Cool

Is there any way to play this on Android devices because every time I try to run it on the website after I select story mode it loads up and then crashes with a gray screen with a not happy Square emoji
