Criticism in the knowledge that this is a prototype.
- There should be moveable sliders for the audio in the menu
- Linguistic comprehensibility is given
- Dialogue sequences are understandable (speed)
- Getting into the lift takes some getting used to
- The sound of the banister swinging up seems inappropriate.
- Running fast seems unnatural (as if on rails)
- The acoustic ambience at the deja vu is used very well, especially when the shadow appears.
- There needs to be some visual or auditory warning of the shadow's appearance.
- The shadow needs some agility
You're on the right track.
