Hi, in my EU country the game is not shown on Steam, the only TLS linked thing is "TLS - Yarrah Thanks" which disappears from the search if you look fully worded for "The Last Souvereign".
I dont mind bcs i buy my games preferably from GOG or Itch or Patreon (GOG would probably also not show the game in my country).
Though, i switched to Linux Mint recently and wonder if the game runs in a Linux environment?
