Hey there,
Sorry about the anti-virus flag. There shouldn't be any issue with the executable; it was generated directly by Gamemaker: Studio 1.4 and is the same version of the game we've distributed on itch.io for the last year or so. I'm not super familiar with the ins and outs of McAfee, but I know "false positives" can crop up for various reasons. I think the best reassurance I can offer is that the file you downloaded has been shared and run by many people with no issue. That said, I totally understand and appreciate your caution!
Hope this helps,
