After getting hands on a Steam Deck found a major issue, I've found decals didn't work due to OpenGL was used and don't have compatibility with the kind of decal rendering the game is actually using. Which means Linux/Steam OS now is using Vulcan. And I glad to communicate that the game is running at a steady 60 FPS (with the highest presets) on Steam Deck. Other matter at hand was I forgot to implement a way to make the user be aware the Tombs are near to be opened. I thought leaving the footsteps could be enough, but unlike it's predecessor (Oh Mummy!) the footsteps in Tomb Stalkers are more a guide than a way to know if the tomb is to near open. So now, damage to the tombs appear when you walk around them: the more cracks appearing, the nearer to be opened they are (as depicted in the image below). This way, users always will be aware visually if a tomb is near to be opened buy the amount of cracks on top of them.
Soon Beta 1.7 will be available to be accessed by press and content creators interested. Kind Regards, Gara Rosales Gonzlez Itchy Games
