UPD. There was a terrible bug in the first version of the game, and I never knew about it until my friend played it. If you want to play with less confusion and without restarting the level, please download the fixed version.

What is fixed: main mission objects not spawned after the lights goes off + cube not following you.

Collect all the listed items and try not to die in the process. Beware the cube!

WASD, Space to jump, E to interact, R to restart.
