Well, this is a weird one...
Without any instructions the first thing I did is escape your carefully cubed in map through a gap, with no clue what to do next. Killing myself using fall damage and choosing to retry didn't get me back into the main game area either.
One restart later I noticed the red pillars and followed them, reading the hint about the boxes, going into building and hearing scary sounds, but was never in any danger. I even walked back to the apparation once to make sure. Getting the hint about the lights led me to pull the first lever I could find, which was actually a monster? I thought I was protected because I pulled the lever and promply died :D After pressing retry I just ran somewhere and arrived at the ending. Pretty sure I skipped quite a few things.
All in all: This might have become interesting with the protecting light and the monsters (and candles? never saw one, I think?), but I was able to run straight through to the ending by accident.
