I would like to request an any% category since the game plays the ending and credits sequences upon completion of the 90th level in the game. Timing is similar to the 50 levels category except it would end after the screen flash after the 90th level. Just a note that to check the in-game time after viewing the credits sequence, a soft reset has to be performed to go back to the title screen. I think the ending sequence can be skipped by pressing Start to go back to the map screen without having to watch the credits, though.

I recently uploaded an any% run on YouTube and there might be strats that can push the 50 levels category down further.
