you need to work on the jumping. It is clear that the change of gravity is focused when you walk on a corner. However, when you jump off a corner and you fall down to you death, there should be some kind of mechanism that would gravitate you back. Just like how planets work.
You need to change the mouseMove event to an enterFrame to avoid the scrolling hack. Also the game idea is not that original, i've played this before (about the do not copy thing).
The game is cool but i just have 1 complaint. It is either far too zoomed in or the flash app is too small... I have to look 80% of the time to the minimap
