Super Meat Boy Stage Difficulty
This section will include my personal rating of the levels in Super Meat Boy in terms of easiness to clear. Obviously, this will vary from person to person, but it's a decent reference point on where to start your no death runs.
NOTE: This is a preliminary rating that I came up with after playing the levels a couple of times. The final rating will look a lot different from this.
