Canabalt was a great game but this is nothing like Canabalt.
There is quite a bit of ingenuity and thought that went into making a game with a single user interaction (tap on the screen) but with also a fair degree of sophistication and strategy/decision making.
I've only played through about 6 levels and am impressed by the game play mechanics they have introduced with a limited interaction model.
