Spheres Of Darkness

BEWARE: Contains fast flashing pixels.

I made this game for the Godot Wild Jam #46 in less than 8 days.
Its more or less a horror game. No JumpScares, No Blood/Gore.
My current knowledge in 3D-Gamedev: Low

Find 3 glowing white spheres in a dark dungeon. Beware of the black spheres. They dont like you.

Controls:

WASD / Left AnalogstickMovement
Mouse / Right Analogstick
Look

Known problems:

- Fear shader does not always reset
- Performance-issues (if someone could tell me why, i would be very grateful!)
- Speed-balacing is not good

Hint 1

The white spheres add parts to the dungeon. You can then go to previously unreachable areas.

Hint 2

Torches go dark behind you when you go in the right direction. (not immediately)
