Well it runs on Steamdeck and pretty well actually and not just for me.
But yeah you are right on that, instead I should have noted it while not specifying Itch.io to mark it as Linux, I thought it was meaning compatible with and not native. In fact when I used butler I could choose which channel to publish to. And a channel is made specifically for Linux native build. Meaning I could have a windows build marked compatible with Linux. But it's confusing... I am completely new to itch and well making games in general I am far from being a dev in the first place.
I tested and worked on a native build, turns out with fmod, some third party plugins etc, I have compatibility errors. I am actively working on replacements to make a native build. The one I have is working but sound is broken.
Thank you for spending the time to write your second message, I can understand that "it's a tactic you don't tolerate" but it was a guenine mistake when I was excited I could play this on deck.
