I just have to remember to call the selector from the right table - I kept bumping into bugs where I was calling the entire table instead of the value at i
Also updated script below:

Still need to figure out how to handle doors and the spring ball enemy, but it no longer shows health bars for projectiles and Gamma Metroid barriers.
EDIT: Removed one check since it was ultimately redundant.
EDITWO: Added a sanity check to getEnemyStats()
