You deleted my comment interesting, you should mention to download the game through internet browser and not through itch launcher to avoid confusing the users as it gives an error.
Helping with unzip issues!
I saw a few people mention they are having trouble un zipping the game.
First off you need to grab the Ver1_5 file and NOT open the zo1 file. You need to use WinRar to open this
Doing this will extract both the zip adn the zo1 file into one folder and connect the files together. As itch has a file limit its not easy for us to just upload a 7 gig file so they need to come in parts. Only once you have done the above will the game work.
