Meat Boy was one of my favourite flash games, but this retail version takes the formula Edmund McMillen created and perfects it in every conceivable way. The controls are beautiful - Meat Boy's movement feels so natural, and every death is by the fault of the player, not the control scheme. The level design is also fantastic, with a huge range of mechanics gradually introduced to the player, meaning boredom rarely occurs. What really impresses me though is the HUGE amount of content the game offers - hundreds of levels ranging in difficulty, with even a level editor thrown in there for some extra fun. The game's biggest flaw is a poorly designed boss fight around the middle of the game, but this hardly distracts from the awesomeness.
