I actually have a bad sense of direction so the first time I played through I somehow went far enough to fall through the floor! haha That aside, this is a very insteresting game considering the custom engine. Hazel engine is actually new to me and I'll look it up later to see more about it.
Now, on to the gameplay itself, running should have some kind of stamina bar, I felt like if I ran non-stop they would never catch me.
Even so, after I noticed this, I tried playing it without sprinting so much and got the sense of delaying impending doom, so good job on that.
I liked the lamps as a visual cue, but this takes me to another point: I think the map was TOO dark. I mean, I know this was probably to set the mood, but I very much would like a more somber approach instead of plain dark and a few really bright lamps (does that make sense?), maybe it was just me though.
Speaking of setting the mood, you did it really well.
Great game!
