Really cool game. I cant give any praises that hasn't been said. The music, the feel on the computer, the puzzle...
However, I do have a few critiques (mostly neat picking, so don't listen to me):
-There is a bug (i assume) where you can close tabs even when the x is hidden. So that is a bit bothering
-If there was a metaphor or smth about the file being empty, i did not get it. I feel like that is on me tho
-I feel the theme a bit vague, since you are basically pushing a button, not so much spinning it. But I am usually harsh on the theme application. (Not that mine is good or anything)
-This is 100% personal opinion, but I don't like being presented with a "dilema" (in this case, given the chance to enter the computer but this computer/haker/IDK telling me to please not enter, that it is his sanctuary and we are intruding) and not being able to decide what to do.
Overall, solid 9/10
