GAMEPLAY: I do appreciate a game like this having a thorough how-to-play, even if some people don't. I also appreciate a game without time pressure, which wasn't the obvious route for a game with time as a resource. The base mechanic is a nice one, and it was a bit puzzling going through my files for what fits (or sorta-fits for extra points). I think it'll work best with a broader task pool, though that's very much a scope thing.
VISUALS: The UI is wonderful, on-theme, both pleasant and informative. The icons are... crunchy. It looks like the default icons were upscaled, making the lines all wobbly. The style's fine, it just needs cleaning up.
AUDIO: The clicks are old-school and satisfying, but I'd expect them for every click I make. While I like the choice of no background music for the setting, it did get boring after a while. I could see an expansion on this having other desktop apps for things like turning music on (having it be off by default).
THEME: The computer space feels a bit limited, but even attaching my computer's kernel is out there enough.
