Small update

An update to add some things missing from the Jam. 

Added:

The player takes damage and has an end screen for running out of life or reaching the top platform. Arrows firing with the correct facing and placement. Lots of checks for resources and timing when switching and use of specials, infinite jump fixed, boundaries to not fall off the edge, shield power-up now implemented.

Still Missing:

Sound

Lance Attack

Boss

Enemies the entire way up the tower

Blocking progress before camps if enemies not defeated
