May i ask how do you get pets ?
I currently don't know how to use the steam key...
Please help.
If you have a steam account you can redeem the game on steam, meaning you don't have to buy the game on steam. Steam had in-game purchases whereas, itch.io doe not support ingame purchases.You can easily google how to use steam keys.
