I remember i never could get past the dinosaur in Bart vs. the Space Mutants. I thought I'd try again on an emu many years later and downloaded a walktrhough. How the hell was I supposed to know you were expected to jump onto a rock lying on the ground five hundred feet into the distance and then jump onto another rock a thousand feet into the distance and then jump on the exact spot on the back on the t-rex's neck that you wouldn't fall through and die?
