So i have to re purchase for the steam version as well when i already purchased from here? I didn't even know it was on steam...

Hello, Sorry, but yes, Steam and Itch are different platforms, so buying a game on itch doesn't activate it on Steam. But you can always add the itch game to your Steam library https://help.steampowered.com/en/faqs/view/4B8B-9697-2338-40EC
