Hello gamegenie, that's a weird error. Apparently, the game can't find the Mono.dll file that is included with the game. The fact that both Steam and itchio versions have the same issue, makes me think that maybe your antivirus or Parallels are blocking the file. One thing to try would be to uninstall the game, install it again, and put a rule on your firewall to allow the program to run before launching it. Let me know if it works. If we can't find a solution we'll make sure to refund the game to you. Sorry for the inconvenience.
