Each code is one-time use — looks like someone already claimed it, sorry!
Couldn't you have thought of any other way to do that I'm in your literally screwing a lot of people out of content that they could be getting that they got legitimately practically every person who has downloaded it from your account I mean you've got to figure some better way to do it because it's just not fair for the rest of the people who actually want to play your game who are actually legitimately getting it from you personally
I understand your concern. I originally wanted to make global codes, but due to piracy and the complexity of implementation, it wasn’t possible, so I had to use unique codes instead. I know it’s not the ideal solution, but it’s the best way I’ve found to protect the project. If you enjoy the game and would like to support its development, you can subscribe on Patreon but if not, no worries, you can still play all the free content available in the game
