Hey first of all. Thank you very much for trying out our game! We did have a discord server for HumanRobotGames. It used to be private but I can bring it public https://discord.gg/4TG3mMGdDK. (there's a whole bunch of art assets, and mostly technical discussions)
As for the steam release, we will look into it. The main thing keeping us tied up is the actual production and photon integration. On top of our day job and freelance stuff. If we get off the ground here, I wouldn't mind paying a fee to get it on Steam.
