Ragdoll Runners

Ragdoll Runners is a physics-based Track & Field game where you control independently the two legs of an athlete to compete in different events: sprint, long jump, triple jump, hurdles.
In Ragdoll Runners, you control an athlete principally with 2 keys (or 2 gamepad buttons): 1 key per leg. A third key is sometimes needed to lean forward: to finish a sprint, a jump, or to jump over a hurdle. Therefore, the gameplay is not based on button mashing like many other athletics games: it’s all about good timing.
You can take part in a solo “career” (series of levels with increasing difficulty), an up to 4-player split-screen mode, or play online asynchronously against any record of the leaderboards (the world record, your friends' records, ...). There is also a dynamic "Challenge" online opponent: when you beat it, it is automatically replaced by a better record from a higher ranked player.
Some claim that Ragdoll Runners is a clone of QWOP. Here are the differences with QWOP:

• more types of events,
  
• computer opponents,
  
• online opponents,
  
• more realistic events: you can do the same performances as in real life and even beat the world records of Usain Bolt in 100 metres, Mike Powell in long jump, Jonathan Edwards in triple jump, Aries Merritt in 110 metres hurdles Maurice Greene in 60 metres,
  
• easier than QWOP (less inputs, you don't struggle to stay up and you're not disqualified if you fall) but still difficult to master,
  
• you can play with 3 friends,
  
• leaderboards,
  
• replays (with pause, slow motion, ...),
  
• astonishing graphics? hum...

Another argument: the first prototype of the game was made 2 years before the release of QWOP
