I'm a rather squeamish person, so I tried to cheese the game as much as possible. The problem is your game stick to the theme so much it pretty much covers itself.
You can outwalk the monster yes, but the lack of light, the audio design choice of only hearing your footsteps, you are very incentivized to keep the lights on. However, certain puzzles require you to NOT turn on the light in order to progress. I can't believe I got engaged by a horror game so much I beat it and 100%ed the collectables.
And the game also tracks that in the extra sections, 10/10.
