Did you try using the itch.io launcher? Im on mac, and ive had trouble in the past with being unable to open games after downloading them myself. I havnt had any problems with the launcher yet.
Zimbwawa you were right! I've never used the launcher. It totally worked. That being said, Keeran, I really liked the idea of the board affecting your playing ability. This was definitely a cool game with a huge potential to be expanded. Great job man!
