I really hate to mention this but the height the character jumps to is out of all proportion to it's ability to clear obstacles.
If you run up to a low wall or fence and try to jump it. The character will jump to 2 or 3 times the height to the obstacle and STILL fall back because it's apparently too high.
This applies even to small rocks lying about the terrain.
It's bad enough not to be able to clear things that I know would be easy for a human, but to have insult added to injury by the giant superhero leap animation...
'Clever' sigs get old real fast - just like this one.
