I am at the top of the house, got confused to what to do next so I peeked at a walkthrough. It says "run and jump at the right corner of the roof". Every time I try that I keep ending up on the lawn surrounded by enemies and fence. I look around and can't seem to find my way out and get killed. Is there even a jump button for the game? I looked at the manual and it doesn't say any thing about a jump button. help please. thanks.

Jump down to the garden, slightly to your right there is a gap on the top of the wall, you need to be standing right under it for the "O" button to appear. Once you have that, just jump over.
