The graphics are nice, but I feel like there are some missed opportunities here. I was hoping to get a cool, addictive mining experience with some horror aspects, but what I got was something that I didn't really fully understand.
We are told to grab a pick axe - but we don't even really use it the majority of the time (and I never really found the opportunity to use it while I was playing). When I ran into the dead miner guys, I thought "oh well this is what the pick axe can be used for", but then it turned out that I couldn't fight off the dead miners and had to resort to running away from them.
I did not think the light effect worked well as a mechanic - where the miners would be entirely disappear when the light was pulled off from them. The dead miners kept accumulating and it felt a bit unfair because at some point I was overwhelmed by them - and didn't even really know it. During my run, I never got to see what the point of the pick axe was as I ended up giving up which kind of bummed me out.
I'd like to see this idea expanded upon and maybe fleshed out a little better!
