Overall: It's a good idea and mostly well executed. Because it's such a "tense" game, when something happens that feels unfair, it's easy to get especially aggravated.
Fun: It's pretty fun for a little while. For me, the obvious comparison is Keep Talking and Nobody Explodes. A big difference (besides being single player) is that there seems to be no victory condition. I think that being able to win - and try more difficult stages - is a big part of what kept me coming back to KTaNE. The fact that this game just goes until I lose means that I don't feel on the edge of my seat quite as much. I noticed an effect, whereby, when I replay the game, some of the minigames don't trigger any more. Eventually I can play the game without anything ever triggering, and survive forever. A couple of other minor gripes: (i) the alerts appearing over the top of the game I'm playing; (ii) the blue text in the colour game is hard to read; (iii) having fuchsia and purple as two of the colours screwed me over. Go fuchsia yourselves.
Innovation: Sure. I mentioned KTaNE (Maybe Spaceteam as well?) but this is clearly different, being single player and having its own set of minigames.
Theme: Yes
Graphics: Not bad. My own preference is to see everything consistently pixellated or non-pixellated, but I guess it's a matter of taste.
Audio: The music sounds good to begin with and is very appropriate, but the loop is so short that it gets grating after a while.
Humor: Yeah, the story's funny, along with the whole situation.
Mood: Good, a tense mood is created by the time pressure and the music.
[Update: I slept on it and decided the fuchsia/purple thing is actually pretty funny. I'm not mad any more. I also need to learn to spell.]
