I tried the original screwed up demo and was majorily bummed. But after reading the reviews of the actual game I bought it. IT IS FANTASTIC!! Seriously! The various environments, sounds, and gameplay make this game impossible to put down after you start! The only drawback is a bit to much on the jump puzzles, but that's like saying you hate free money because it makes your pockets too full.
The levels are superb, and tough, the RPG elements is added just enough to give it diversity without being totally annoying, its all around a really great game!
Who the heck wouldn't want to be a program running for thier life as the hard drive is being formatted, or jump around in routers or PDA's. Plus the humor they have in there is really funny!
You're missing out if you don't pick this up!
