Methinks I'm going to have to check this game out. I do like puzzle games, and this one sounds very interesting. The art style sort of reminds me of Cave Story. So far as difficult puzzles go... yeah, it feels great once you finally figure them out. A few puzzles in Braid took me a moment but they became amazing once I figured out just what I was supposed to do. What's funny about those puzzles you mull over forever is when you start to think there just isn't a solution, and that the game is broken somehow, and then you just do something random or off the wall and it works. Or you try the simplest thing you can think of and the whole solution becomes obvious.
Just be careful if you have an older xbox, because it is apparently glitchy on those, as the comic clearly illustrates. Or at least, keep your dog away. Having one of those space tears could be useful, though. Never have to take out the trash again. Easy disposal of evidence. Easy disposal of people who get on your nerves. Plenty of uses.
