Very easy to pick up and learn, new mechanics/concepts are introduced each level slowly increasing the difficulty. Really gets the cogs turning! I played this game years ago and could not remember why I dropped it, now I realized it was because of the difficulty it reaches. Even if this isn't for me, I still recognize its incredibly smart design. I could see this being an excellent tool for teaching programming. Definitely warrants a paper and pencil to make it really feel like work, fits with the corporate theme perfectly.
