If this can be independently verified, I will kiss you on the mouth. Oh what a relief it would be to "be allowed to die."
Er... no need for that, unless you are cute single lass living in northern California... really, I insist.
Anyway, more specific details.
- I beat the boss of world 6. ("Beat the game.")
- My save file had a single, non-flashy/shiny/whatever star.
- I found a level with a Assist Block (white raccoon) in it. I had never finished that level, and I must have died 5 times while attempting it during the initial playthrough.
- I beat the level -using- the Assist Block.
- I then replayed the level (now with no visible Assist Block) and beat it normally.
- The star on my save file is now shining.
It looks like you can even
recover from using a White Raccoon Mario to beat a level.
I'm seeing folks on the internet saying this ISN'T true, which makes me think that either there is a "limit" (which seems unlikely, given what happened to my game), or that those folks have OTHER levels they lost on 5 times.
The trick here is that once you've died 5 times, the level is flagged, even if you don't replay it and thus never see the Assist Block. It's quite possible to have multiple levels tagged with Assist Blocks but have no clue about it if you weren't keeping track of lives.
(Is it 5 lives that gets the Assist Block, or more? I didn't count.)
