Brother, by God, do you think it's fair that I put a game on 1 platform and after everyone buys my game, I just abandon the old one and release it on a new one along with an att and prevent the people who got the game on the old one from getting it the update? the argument that "the creator didn't know there would be Steam items" is flawed precisely because he should give the keys to those who bought his game, if those people knew that they simply couldn't receive the game even though they bought it from itch.io , they would have expected it to come out on Steam and bought it from there. It's not our fault if the developer didn't have planning.
