Oh, I love this game. And not just because we both went for "exploration in dark tunnels" :D
The atmosphere had me on edge and the mechanic of the flashlight (?) making a noise so you don't just want to hold down the button the whole time is excellent.
Would love a downloadable desktop version though, as some of us have issues with Godot complex 3D meshes on Web (and yes, my game has the same issue).
