Here's a scheme ''Jetter'' which I have put together.
You use the jetpack to pass through a variety of obstacles knowing you have to get crate at some point and once all of that is done, you may attack your opponent.
When it comes to map building, it's up to the individual author to decide the complexity of the map.
The map author may decide to have two maps in one single map. Meaning one simple course of obstacles, and one course with harder obstacle. So once the HP reaches 100 and below, that player needs to go through the difficult path, grab crate & attack.
But again, these extras are up to map makers.
Comments & feedback is much appreciated.
