sorry to hear that bro. How much did they charge you for the physical cartridge? did you have to sign up to patreon to make the purchase?

For 10 month paying 15 USD on Patreon you were promised a game. I did this twice. The first game they actually delivered but after paying 150 USD a second time they only told me that I will have the game before a vaccine against covid will be available. That was the last I heard. They disappeared from patreon and never again replied elsewhere.
