Enemies now deal damage. As per the original, there is a large energy reserve that gets depleted as you get hurt. When you do things like collect heads and place them in the safe room you get a little boost and points. Personally, I think the age of points is over and nobody pays attention to score in a game like this
After you unlock the yellow block digger you are free to explore this area full of baddies. It serves no purpose other than to stress test the terrain and how much larger levels can be made.
FREEEEEDOMMMMMM
More soon
