- Ghost

would be great.
-I have no problem with the 3-lives in the Warpzone, but I hate to have go back from the main screen and have to see that freaking animation again. This just ruins the flow of the game. If the player lose his three lives, just kick him back to Level 1.
- Be able to set Meat Boy to always run mode (and pressing the run button would make him walk instead). I have finished the first 5 chapter with 100%, but if I remember correctly there were only 2 levels (+ the Kid warpzone) where I didn't hold the run button the complete time
-Be able to play the previous level without going back to the map screen, currently you can only play the same level or the next one.
