itch.io

You can still back the game and all connected files up by saving the frame (firefox).
Having a downloadable version/container would be cool ofc.

The official itch.io app lets you download the game to your Windows, Linux, or Mac computer for offline play with automatic updates. I believe you can do something similar on Android using an app called Mitch.

If itch.io takes the game down, I'll make sure it's hosted elsewhere & I'll write a post with the link.

I may also make it possible to download the game file once I've finished work on it.
