While I won't reflect this in the rating, I absolutely hate when I hop on newgrounds to waste a bit of time, see a promising game thumbnail, click, then see that I have to sign up and go through the "create a username" crap. I can't find the back button faster.
Though in fairness, since I wanted to spew my two cents, I should play to give a legit review. First off, my first email was invalid, aggravating. Second, the game is slow-paced, like ridiculously slow. It's like Star Trek, something interesting only happens once a week, the rest is trekking. I do like the graphics and concept though, but that'll only get you 1 1/2 stars.
