For an Xbox Live Indie game, you'd be surprised it isn't an Xbox Live Arcade game. Retro indeed!
I would suggest looking up some videos of the gameplay because it is virtually the same in all levels to a degree, just different obstacles to navigate through but same objectives. No save option however, which is better for that retro feel. You shouldn't be able to save to a point where you can F around without consequences, like the original platformer games like Mario or Sonic, etc.
So for fans of the old retro side scrollers, this is a must get IMO, especially with the price of only 240 MS points. Unfortunately, there are no achievements since it is an Indie game. So if you got left over MS points you don't know what to do with, use 'em on this title!
