So I played the Original PC Spider-Man game back in the day. One of my first proper video games
And so, there was a level where Spidey was running from the Law. And at one point, he comes to this incredibly tall building, with an even taller cage of construction beams on top of it.
What you had to do was climb up to the top, and continue running from the police, but I didn't know that for a while. So I'd just play from the beginning to that point, and repeat.
After I discovered what you had to do, I went on to explore the 80% of the game I was missing
