It's not often you'll find yourself so immersed in the story of a game about a blinking square. To reiterate the point of a previous commentator, I recommend opening several tabs/windows after obtaining anti-grav, selecting "Continue" in each to essentially create save points. Then explore. I upped my rating from 4/5 to 5/5 after I used this "cheat" to avoid the repetition of starting from scratch.
I "beat" the game by right-clicking and clicking Play. Srsly. Kongregate even gave me an achievement for it. Gonna play the game for real now. Great, hilarious voice acting so far!
