update! now not even the mouth loads ☺️
Not a known issue, no, but with the huge number of different devices out there I'm not surprised there might be incompatibilities between the engine and some gfx chipsets / their drivers. What device are you trying to run the game on? How much RAM does it have? My best guess is that it's either an incompatibility with the gfx chipset and/or not enough RAM to run the game reliably (RAM is also shared between regular and video memory)
In any case, I strongly doubt there's much I can do about it. The game is coded at a much higher level, and relies on the engine (Godot - similar to Unity) to handle rendering and all hardware interactions.
