Good evening! I'll release details soon!
For clarity, Steam keys will be made available per request for players who bought the game on itch.io during a certain application period. If you own the game on Itch, you're applicable to a copy.
If you purchased a copy of the game on itch.io prior to or during that period, you'll be eligible for a Steam Key. This is mainly so that we can check who owns the game proper and assign keys to those buyers. Keys will be sent to the email linked to their itch.io account.
