Hi itch.io

I'm Brett Ridel, the main (and alone) developer of Sparkly Games. 
I just published my first game on Steam, and I would like to publish it too on itch.io, both for future players and also for press (free for them, of course). 

 I'm annoyed to ask because I know it's not perfectly compatible with your principles, but I would like to distribute only Steam keys, and not an archive of the game. Indeed, my game is a VR game that need SteamVR, and the Steam API in general. If I distribute the game as an archive, users will not be able to use some features of the game, such as ranking, which is one of the core features.

My itch.io related project has been accepted, but because there is no downloadable content, no one is able to purchase it.

 Cordially,
B. Ridel
