Thanks for the suggestions! I'll get a Linux build from Unity next... bit hesitant to do so as I don't run Linux, so won't be able to test if the build works or not — but let's see what happens!
I'd love to run a Patreon, but I feel like I don't have enough content to keep it going long term... But sure, this is something to think about.
I'll post an update once I've added linux support!
Thanks for reaching out! I really appreciate it.
