Please make this claimable so that it is added to collection, thanks!
I'm a little embarrassed to say that I am not sure what you mean by claimable. Can you help me out? I don't see any toggle for it.
Set a price for the game (like $1 USD or any other amount) then provide it at 100% discount.
At that point, the 'paid' game should have an option in the developer settings to make it claimable unless you explicitly disable it.
