Hey, i absolutely love this game, but recently when i was running a virus scanner on my mac i noticed that it caught something within your game called backdoor:OSX/CrossC2.Cobalt, which after some googling told me that it's a cross-platform malicious payload generated by CrossC2, which can allow attackers to extend Cobalt Strike into a few different systems.
As you can see in the image above, i have the option to repair such files, and when i did, i was unable to open the application afterwards. this has also occurred for other games i downloaded from itch.io, such as Incursion, another well-made and legit game which i have played before.
I don't know if that was added to the file after i downloaded this game or not, but you should probably investigate that sooner rather than later, because i love this game but i can't play it until i know its safe again.
