Oh no! D:
Unfortunately we don't have a great way of testing on Linux Mint.
So sorry you don't have a chance to play our game :(
Linux Mint is a derivative of Ubuntu, so if it works on Ubuntu 16.04 it should work on Linux Mint 18. I have noticed a lot of problems with my system, though, so I'm hoping that when I do a fresh install it will resolve the issues I currently face and I can play the games that currently bug out.
