I don't like the Boost at all. But what if it was just an armor boost and nothing else?
Sorry if this was a pointless bump. Armor would not be as difficult then speed and Health.
1. You can goomba stomp them(Which is pretty much what all the people do as the last human is alive).
2. They take fall damage.
3. No speed boost. Meaning you can hit them.
EDIT
Also the Armor will simulate the Health boost. But you take fall damage as normal.
