2. Combo of Mario and Ghost'n'goblins (A Little XD) with some acrobatics/aerobatics.
3. Preferably not across flatground but down stairs, depending on how fast they entities are traveling they might hit stairs on the way down (a bump, I guess)
This is what the third sample looks like so far, not all textures are made yet - while a few are place holders.

So i'm technicly following the third alternative at the moment.
Edit: Tiny change.
