itch.io

I've answered my own question in the easiest of ways: Download Kira Studio portable Windows build, add the .exe to your linux steam library as an external game, configure to launch with the latest proton, et voilà! It works!

Hi! How can I install it on Linux? Is it available on Steam for easy installation and execution through Proton, for instance? Is there a linux tutorial out there?

I already own the game on itch.io and don't receive updates download emails anymore, why ?
Awesome game, BTW. Sank many hours in the android version.

Oh god this was so much fun
