The japanese sm64 community created a challenge where you have to play through the game without taking any damage, and if all 120 stars are collected, start over again and keep playing until you are damaged. The leaderboards for this can be found here: http://www31.atwiki.jp/sm64/pages/17.html

Would anybody be interested in starting this type of thing for meat boy, where you play through all light levels and keep repeating completions until you die? This sounds like it would be a fun, alternative challenge that could gain some popularity.

So, it's like the opposite of a speedrun? The longer the run is, the better?

the further you can play thru the better

You would have to leave out glitch girl, kinda silly if you dont

nah just exit to map None of that double switch char during levels cus you could jsut use that to cheat death
