There's a lot of glitches with the tutorial... For example, my mission objective is "Escape!" But... nobody's chasing me, and it doesn't say WHERE to escape to. Other than that, seems to be a pretty solid game.
I'm a little confused on the mechanics. Is a high rate a good thing or a bad thing? Some levels give a -1 rate, where when you get all ten points, you get a +3 rate bonus. Kinda confusing.
