Review by Brad Gallaway:
"How much entertainment can you get out of riding down a hill on a sled? If Line Rider 2: Unbound is the ruler you're measuring by, the answer is: not much.
I had never heard of Line Rider before seeing the retail copy arrive at the GameCritics offices (i.e., my mailbox) but after a bit of research, it turns out that the inspiration for Unbound is a Flash-based program available over the Internet. More an interactive toy than a traditional "game," the developers have tweaked the formula in order to make it a bit more appealing to handheld gamer sensibilities and turned it into something of a puzzler."
