If you're a kid with finely-honed, millisecond-sharp gaming instincts, developed over years of repetitive play, you'll probably have a great time. If you're a grown up who, like me, thought you were buying an enjoyable game whose primary challenge is puzzle-solving, then you're screwed. The game is gorgeous, easy to learn, and easy to play. The levels and puzzles are challenging and fun. But when I came to the first BIG boss, the T-Rex, I got destroyed. And then again. And again. And on and on and on... It's one of those shooting sequences where you have to hit EXACTLY the right sequence of keys, at EXACTLY the right millisecond, and then do the whole thing over again several times. If you make the slightest mistake (there's ZERO margin of error here), you're dead, and have to start all over. After 30 or 40 tries, I said "screw it," and packed up the game. Thirty bucks, flushed. Oh well, live and learn. Grown-ups: stay away. Everyone else: I'll be selling mine on eBay.
