Medium Rare: Meat Boy
Do you like your platform games ultra-minimalist and covered in blood? Then you will enjoy tricky browser-based platformer Meat Boy, which I discovered thanks to the sterling data-mining of IndieGames.com. Meat Boy, you see, is a bleeding chunk of flesh with a distinctly jumping-based task ahead of him: defeat the platforms to rescue Band-aid Girl. Leaping and wall-jumping to victory, Meat Boy leaves a trail of blood spatter where-ever he goes. See, I knew you'd like it. A direct download is available here.
