Unfortunately not. I might be able to make a platform-agnostic version using Mono, but right now it uses p/invoke functions from SFML.NET to render everything. I think I can move it over to Mono-compliant stuff fairly easily, though, so I'll try and do that when I get a chance.

tl;dr, not in it's current state, but I can probably modify it to run on Mono for a Mac with minimal effort.
