Fix for linux versions and itch app

Very excited to have the itch app downloads and installation fixed for linux. All I need to do now is fix up my Makefile with an extra build process for an AppImage and add the push via butler and we will be all set with small cycle times and future games.

Luckily a few brave souls have gone before me and paved the way with some great tools to help make this distribution the easiest in my experience.

Please try the game out and let me know if any issues, I appreciate ever piece of feedback I can get.
