For those who would like to try there is now an UNSUPPORTED Linux version that you can download and use if you buy or have bought the Windows version. This Linux version is unsupported and comes with no promises whatsoever.

I'm still deciding on whether I officially want to start supporting this because it's extra work for likely little sales and possibly more bugs & issues (e.g. sound is possibly glitchy or completely broken).

Anyway, on the positive side: Give it a try if you have Linux and let me know how it goes.
