The 1.0 version of microrail for Mac was available as a free download on our website. Microrail for Mac relates to Games. This free Mac application was originally developed by Kirkjerk.
From the developer:
Microrail is a tiny world of a not-super-innovative but solid and fun puzzles, where you make a rail line by connecting two specific endpoints. When it is solved, every white station will have 2 rails connected to it, and the blue station will have only a single rail.
