Gave Mr. Crab a whirl the other day–really slick game. Controls are uber simple but its still a really challenging game when you get further into it. And it looks outstanding! Its great to see someone make a good platformer for iOS. Touch screen controls are often too clunky and lack the fine precision need to get a platformer to feel right. But Mr. Crab works perfectly on iPhone/iPad. In my opinion this is a must have for anyone who owns an iDevice. Pick it up–its only $0.99.
