I can add a start in fullscreen button. I don’t think the engine is compatible with the overlay tho. Tried a couple of solutions and none worked.
That's too bad, thanks for trying. I'll just play it on my steam deck instead. It works great with the game set to proton experimental.
Also, a start in fullscreen option would be awesome. For controller users who got a second screen as their tv who don't want to run back to their keyboard to press f11, that's a game changer, as niche of an audience that sounds like. Lol.
