I didn't purchase it through itch but my friend gifted it to me so how would i do that
I don't understand. How would you do what, ask a question on the game's official page?
When you say your friend gifted the game to you, what did you receive? The game attached to an email or an email with a link to itch.io?
A link to itch.io which allowed me to download the game bc she bought another copy for me
