Hi Zeeloo! Thank you for checking us out. Can you tell us which system you run (Windows or Mac + version), and whether you're trying to launch the game directly or by using itch.io client?
No problem, Zeeloo! There might be some issues with itch.io client (we haven't sorted them out yet), so if you don't want to wait, I suggest downloading the game directly from our website (http://www.uof7.com/minotaur/), unpacking RAR and launching Minotaur021.exe
That should do the trick! But let us know if it doesn't.
