Heya. I think that would mean a Steam key would also be claimable, and I don't believe Valve like that sort of thing. :( So it's currently free as an itch download but still purchasable on Steam. A compromise of sorts...
Yeah, I just claimed Hiding Spot because it's also on a 100% sale, and the description says buying it includes a Steam key, but I didn't get one. So I think you're fine there.
