Can you tell me what exactly didn't work? Did the steam key not function or did you not even receive one yet?
This is not your issue as the author, but in order to receive the key, I need to link my Steam account first. However, at the final step of linking Steam, after selecting to bind, I return to Itch and get an error message saying the binding failed. I have tried changing browsers and disabling plugins, but the issue persists.
