Thanks. I guess everything is ready to be recorded, but I don't want to hurry with this. The completion time will possibly be under 7:40. (To demonstrate, I perform one obvious improvement in the end of the movie below.)
I tested the newfound ladder trick with longer ladders and, lo, the graphics got really messed up. Here's the messy movie:

The trick works like this:
1) stand near a ladder
2) press up for 4 frames ---> hero starts grabbing the ladder
3) press left ---> hero starts turning left
Now, the hero has grabbed the ladder and started turning at the same time. If you then start climbing down, the hero moves down, but his animation is screwed. I guess he is virtually/visually turning while climbing. If the ladder is long enough and you keep climbing, the game runs out of images (of the hero) and an overflow occurs. Something like that.
OK, we have graphics messed up. What then? I ran out of ideas...
