Thank you for checking out my game :)
I could still make a build for Linux, but I don't think you missed anything. I had music in the game at one point, but there was a bug where very rarely two songs were playing at the same time, so I ripped out the music system entirely and didn't have time to reimplement it in the end.
Making a tutorial and telegraphing what is happening should've been more of a priority, you are right.
(Boomer and Spitter were actually a reference to C:DDA - but maybe they got it from L4D)
Edit: Made the Linux Version, but I have no way of testing it sadly
