What I didn't like, is the tutorial is separate from the game. It would be awesome imo, if there's a tutorial stage where the game is explained hands-on (maybe pausing the game with explainers, until I start to get how to play) Otherwise I have to memorise the instructions before trying the game.

Regardless, amazing little game.

I found that even on the easy level, the number of processes keeps growing slowly, and there isn't enough CPU time to keep all processes satisfied. I feel like the game is inherently setting you up for failure. Here is the script if anyone wants to play with it:

  // ==UserScript==
  // @name     Auto-play "You're the OS!" game

Sounds like that black mirror multi-part episode "White Christmas".

Since when have games become more about just completing boring tasks and not about using your mind and dexterity to kill evildoers? Hell, the original Space Invaders was 100x more fun then this, and all we had to do was press a button to kill advancing aliens.

Like has someone invented a novel scheduler or sorting algorithm?
