Cool concept and a nice vibe, but when I gave it a try I struggled very badly with how dark the game is. It doesn't look like in your gifs for me -- I see the game, but anything more than a couple of feet away is engulfed in near-black shadows. With the deathpits around, this results in me walking verrrrry slowly and staring at the ground, rather than chainswinging around like I know I ought to.

Cool concept though! If I could perceive the world I would have spent more time with it.
