The life of a Games Programmer: Collision detection...

(via)
Lemmings never did full sprite to background collision checking, in fact all it did was test a pixel at the feet of a lemming, into the mask. And you could do that directly in GML if you wanted to! In fact, Lemmings had a "1600x160" play area, and you could easily convert this to a 200x160 "BIT" per-pixel mask.
