I am, yes. The 0.4.3 .zip doesn't have a bash script (the .sh file) to launch it. I tried copying over the bash script from the 0.3 version but the errors seemed to be caused by some missing libraries.
I don't think Itch recognizes it as Linux compatible either as the windows versions that are compatible have the Linux penguin icon, and the new version does not.
Thanks for taking the time to look at it though!
