That is one tough cookie, I've been working on it for the past 7 hours since I got off work and finally took a break, I usually end up with the 6th death on the final puzzle =/

This is my second night playing the game after work, and I'm like 75% done with the game, and I've died approximately 5.4 billion times. 
 
You people are crazy, but I fully endorse you.

I was playing the game about a week before launch, and I took a look at the leaderboards. Let it be known that I practically shit my pants when I saw a guy had unlocked the "Complete in one sitting with less than 5 deaths" achievement BEFORE  unlocking the "Complete Limbo" achievement. 
 
Yeah, that's right. Somebody got this achievement on their first playthrough.

Alt account most likely. "

I just got it. Only died 3 times.
 
Funnily enough, 2 of those deaths were in a section I thought would give me no trouble at all.

Plan on S-Ranking this so I guess I might as well start trying my hand at it. 

This seems downright impossible.  I'm going to give it a try though.

How do you even do this? There are so many parts in this game where I absolutely know what I have to do and yet still die 5-15 times until I get it right.

I'll get this eventually but I'm busy with other games right now.

I was really trying for it at one point, could get about three quarters of the way through before dying 5 times. Then Dragon Quest IX came along and I haven't been on it since.. D:

I dont know if the 110% completion is worth the headache

I would like to S-Rank this game, but I'm not sure I will find time. Realistically I could take my 360 to work on night shift... Maybe I will get this achievement.

Had a couple of runs at it this morning, managed to get it down to 7, all on piss-easy jumps as it goes. Might have another go tomorrow.

Seems rather a ridiculous achievement, to be honest. Scary scary achievement. I'd be rather wary of anyone who has procured it.

I did it today on my 3rd complete run through of the game. I practiced the final couple of chapters a few times and did the beginning half or so a couple of times. I did it in four deaths and two of those were RETARDED.

He'd have to be a genius with insane timing for that ending. "
