The game starts off well, but I feel some of the puzzles are very long winded.
There is a lot of walking down long pathways with nothing happening.
To help improve this you could speed up the running mechanic, or shorten the distance you have to travel, for example traveling back to the car is a very long walk down a pitch black road, just to have to turn around and travel back.
I also encountered a but, when I was "attempting" to traverse through the swinging hammers, one pushed me off but the game reset me back into a place where I wasn't able to move and died instantly. You can see this toward the end of the video.
I'm not bashing your game, I think it has a lot of potential.
Just a quick question, how close was I to the end of the game?
