Idk if anyone can help with this but it says "Cannot be opened because the developer cannot be verified" (im on a mac) and idk if theres a way to fix it.
Had a mac and had the same issues for games in itch but I'm pretty sure you go to your system preferences and then security & privacy and you'll see the game was blocked and if you can't click the "open anyway" it is most likely locked so click on the "lock to make changes" unlock it and then now it is unlocked click "open anyway" to open the game. Hopefully this helps lol
