It's no Order 66
Code 7 has some interesting ideas going for it: an intriguing sci-fi story, a straightforward-yet-satisfying text interface, and little real-time minigames for puzzles.
But the execution is overall lackluster. The writing isn't very good. Command-line challenges feel contrived and silly. The minigames are ... pretty dumb, frankly.
When I compare its "hacking" elements to similar implementations in Hackmud or Pony Island - which had problems of their own - Code 7 doesn't measure up.
Also, at least in the demo episode, most of the voice acting is really, really terrible. (The main character does fine, but the rest are quite awful.) And the game has an annoying habit of letting its speech-to-text transcripts get way ahead of the spoken dialog, but still makes you wait for the actor to finish talking.
Code 7's neat ideas are wasted on this amateurish production.
Progress: Finished Episode 0 (the free demo).
