Thanks for the feedback @nitrofurano!
I've released my other games on Linux, but haven't had a chance to test The Last Survey on a Linux distro yet. Since the game is still in development I haven't got around to it... but if you're interested in volunteering to test it and letting me know how it runs, that'd be great!
Otherwise, I'll be sure to let you know when I release a build for Linux. Thanks again!
