It's a short, sweet little game about going into a cave. :)
Joking aside, I liked how straightfoward this was. I'll admit that I had to restart a few times because I either got stuck somewhere I could get out of, or I collided into a wall and couldn't get out. I'm a bit ambivalent about the lighting. It does add to how unnerving the cave is but I felt like it didn't help with navigation when some of the collision for the rocks felt a bit off. I often felt like I was getting stuck when I wasn't actually running into something. Overall, not a bad game in any way. I'd have laughed if we found any remains of anyone who had ventured in before we did.
