Ah, Toy Story 2 for the PS1. 11 years later, and I'm still stuck.
Great game - but almost every level has those platforming parts where you have to climb RIIIIGGGHHHHTTTTTT to the top of the highest structure possible. And if you mess up a jump......down you go. Its really annoying when you mess up right near the top and have to climb all the way back up.
The worst is Level 5 - although Level 4 and Level 10 have the highest drops. Level 4 is a construction site where you have to climb right to the top of the infrastructure to a block of apartments to face a boss who pushes you right back down. Level 10 is on the Elevators and you have to first grapple your way through the ventilation shafts and then play hop-scotch with the elevators until you get right to the ceiling. Its actually worth jumping down just to be amazed at how far you fall. And yet you never loose any health when you land. Buzz Lightyear must be made of Dalekanium....
Oh, and Zurg's one of the easiest bosses in Video game history.
Its a shame the Toy Story 3 game isn't like this, but I suppose you need to cater to a new audience.
