In those years my English was quite basic. I abandoned an adventure in a mine in front of an elevator door because open and every other verb I could think about didn't work. Very frustrating but I lived on and forgot about it. A few years ago I found a walkthrough on some retrogames site. I checked that location and... slide!
I finally have the thing I need
I am in the right place to use the thing such that it will fix whatever problem so I can move onwards
How hard can it be to figure out how to ask the game to use the thing to fulfil its purpose?
Quite fucking hard, it turns out. Quite fucking hard.
