Well I finally did it.
Replaying the first level wasn't too bad. Much like many meatboy levels, once I'd gotten round it the first time, doing it again only took a few attempts.
The second level took about 5 hours. Why oh why can't we save the replays? I must have had over 1000 deaths before I managed to get down that third elevator. Fortunately I got up the 4th elevator on my first try.
I didn't really have any problems with the 3rd level though. I just took it slowly, probably jumped way more flying spikey barriers than needed, but it didn't take too long. This was the only level that I could actually get a "feel" for the character. The other two were so cramped with nowhere you could run and jump.The whole time I was wishing I could play the kid on level 1-1, just to let me get a feel of his movements.
I have to say I'm a bit disappointed having unlocked him. He's not as useful as I'd been led to believe. Still nothing beats the sence of relief that I NEVER HAVE TO PLAY THOSE LEVELS EVER AGAIN!!!
