Wow, thank you. That's very kind!
I'm happy you liked the system! It was fun building on top of an "engine" that already existed and have more time to focus on gameplay content and ideas.
I checked the .exe and it actually did not work on windows either, it crashed on startup due to a stupid bug. Thanks for letting me know. I've fixed it now and it should work on a steam deck as well. I got it to run on mine using the "Proton Hotfix" compatibility tool. If there's any trouble let me know and I'll make a linux build as well.
