Will you make sure the game works well with SteamPlay/Proton? Would be useful for Linux Desktop users and SteamDeck users alike.
I mean it will probably work with Proton even if you do nothing but cant hurt to check and make some tweaks if neccessary to get the SteamPlay "Playable" rating.

You might want to look into the name format, Steam makes a mess of the demo name in my library.

They actually couldn't care less about your suggestions. I had a long post with suggestions and a couple of bugs listed, and they just deleted it. The tone of my post was very positive. There was nothing toxic about it at all.
