Hi! Don't worry I understand, the game is a .exe file so maybe because of that the warning is shown, I can garantee you that there is no virus on the files, and there is a lot of people who already download the game that could do it too, but idk how to make you to trust me so if you don't feel good about it is ok and you can request a refund here: https://itch.io/support
Feel free to also ask to anybody who already play the game if they have any issue with it.
