1) Any videos explaining how to use the new setting like ghost jump and many new features in BB2?

2) also where to setup the gravity for the game field, it suppose to be in the setting middle/second tab in BB1... but i just couldnt find it in BB2?

3) can the character have different weight and have wind force set into the game field? how to do it?

4) can the character stick to another object, only jump or shoot again when the next tab?

Thanks...
