Really cool idea. I like how you flipped the theme on its head. Hiding in the files was a pretty cool mechanic, and I like how many different enemy/traps you got implemented.
I did feel that the darkness was a bit intense, and some of the traps were a bit hard to identify. Like the spikes were hard to see, and there was one room, that Trashcan room, that I’d die before I could realize it was there and it would suck me in from the side.
Its a really good start to a game, and I like the customizations you added for the character. With some polish I could see this being even more fun! Really well done!
