I suppose it's doable, I manage somehow to beat dr foetus dark world and collect 70+ bandages. But my fingers are suffering (specially the little one pushing [shift])
Me too! :D Just keep on playing...you'll get 106% ;)
The only difference is that I'm using my ring finger for shift :D
I had a similar problem with the glitch level in world 6. Every time I unlocked, but not passed it and got out of the game, it would disappear. Once I passed it, it stayed there :-\
