Sadly your game doesn't support Linux and using WINE makes the game glitch out on my machine :( WebGL-Builds(for the Browser) shouldn't be a problem as i can see from the file structure that you used Unity. Adding those will lead to more people testing your game.
From the Screenshots I can tell that I really like the UI Design and the ingame visuals. The story is also a nice thing to have.
(Note: Please do NOT say that your game does support Linux & MacOS if you don't include Linux and MacOS Binaries as these indicators suggest that you have Binaries for that operating system. Even though WINE/Crossover exist they're not preinstalled on all systems, If you've tested the game with WINE and/or Crossover state that in the game's description.)
