Welcome to the first edition of Cranky Indie. I'll round up a few interesting indie/free games that are fun to play.
Toribash - A fighting game where you manipulate your character's joints. Watch the included replays for some hilarious kills.
Sumotori - A strange sumo wrestling game where bouts only last a few seconds. Only a 96k download too. It's pretty much luck if you win a fight.
Flow - This one's an old favourite of mine. You sculpt the terrain to push sprites to the finish. Use the number keys to choose your tool.
Free Rider - Basically like Line Rider but more fun. You actually get to drive the bike anywhere you want.
