Hi, currently it doesn't have steam keys attached ... but looking into it, it's simple to do.
I've requested keys from Steam and when they send them I'll add the feature to the Reprisal Universe itch.io settings.
Thanks for your reply. I'm asking because I am planning to take your bundle but Itch.io does not allow us to pay less than USD1 for any game. As your bundle is USD0.63, I was wondering if we could have both the Itch and Steam version of the game if we pay USD1. Cheers!
