ayo if you know how to get it on linux please do tell
heya, it's actually natively supported. for me, i just downloaded the itch.io client (comes as a tarball i think) and it's literally just extract, double click the runner, and you're good to go. then in the client, find the app, download the web based version (it will run within the itch.io clients browser) then bam! i think there's also a .deb version or something, but i personally prefer the web based one, as that way it minimizes dependencies on my system
