Give me sugestions about it.
I wanna share my games, so I dont know how.
Do you mean to give specific people access to your game? You can give them a download key, which will allow them to download it for free. To do that:
Go to your game, and “Edit Game”
Go to “Distribute” and then “Download Keys”
From there you can either create individual keys, or create key groups. Each key will give you a link which you can send to friends to claim a copy of your game.
