That's strange that it doesn't work. If you haven't unzipped it then that could be the cause but otherwise you can indeed run it with main.py but you need pygame and pytmx installed. Hope this helps!
Hm I do I have those installed... I'll retry on linux tomorrow!
Thanks for your interest! :)
I managed to get it to work. Hey that was fun! Very simple idea but also very well executed :)
