Overall not bad, but a few points:
1. The run button basically serves no purpose as there's no stamina bar and you'll be running all the time anyway. Coupled with walking speed being way too slow.
2. Dying to a monster on the stairs resets you to the very top which feels kind of anticlimactic because the section is quite long and with tension build up lost it's quite boring.
3. Throughout the entire chase sequence you basically never see the monster because you can outrun him very easily.
4. The final scene cracked me up because the motionless A-posing figure basically looks like the picture.
