"also you people saying how you beat it in a short amount of time without ever seeing it before, get a life and stop making stuff up. you either didn't do it correctly or you didn't do it at all because the shortest possible time to logically complete the riddle (with it being the first time you saw it) is somewhere around 8 minutes." Huh? Where the hell did you get that from? There is no lower limit dude, the only limit is your speed and intelligence...
You don't need to guess, folks. If you resorted to guessing, you were doing it wrong. I like how it tells you how many you got right though, so you know when you did something stupid or careless (unless one is stupid/careless AND lucky :P). 5 stars for a great implementation of the well-known riddle.
I think there is a bug at some point, there is a level where people are supposed to come from all directions I think, and sometimes it won't start, I only see the door and then it's game over.
I flew solo for 37 consecutive seconds and didn't get the flying solo achievement... also, when I got the frequent flyer miles achievement it appeared as though I had gotten the social butterfly achievement. And what's with poseidon's blessing? I can still die over the ocean!
Too easy for a stand-alone game, but it could be incorporated in a sci-fi adventure as a puzzle... someone gives you a group of stars that form a constellation and by finding the picture you find the person's location in the galaxy.
You really really shouldn't have to refresh the page to start a new game, for a number of reasons: 1) People who use Kongregate Chat may miss part of the conversation, 2) People with shitty connections may want to connect once, then play offline and reconnect only when they want to get a badge, 3) It may take a while to reload... off the top of my head. And most importantly, it seems as though the developer was just being lazy!
