Welcome to the life of a teaching assistant (and/or editor)! The Grading Game by Mode of Expression is a beefed-up version of the arcade-style browser release First Person Tutor. It puts you in the unenviable role of a TA grading papers for a grumpy proffessor who wants his students to get the grade they deserve: a perfect F! Since you're a bit strapped for cash you have no choice but to capitulate, sifting through papers and marking every error you see with a big red pen.
Sixty levels of smooth block sliding puzzling goodness can be a little bit too relaxing, perhaps? Well don't fret, because if you want a little snark to keep you on your toes, Woodhead serves up subtle Onion-style satire with every new level. Taking full advantage of the iPhone's interface strengths, this is a great little time-waster to keep in your pocket.
