This is a really cool game concept! Making use of the filesystem is an awesome game idea!
I do have the complaint that I personally found it hard to tell what tiles were blocking me off and what tiles were just part of the floor, despite the clear color contrast. I still think the maze layouts were interesting though!
I found that it was very clear what components I had to interact with, and the idea of figuring out what components do/don't go in the folder (or what to rename) really impressed me. I would like to say however, I personally thought that the oxygen room was pretty hard to figure out because I thought it was a lot more different than the usual puzzles without much clarification.
Also this really caught me off guard for some reason, I love it.
Very good game and a pleasant art style! Great job!
