beta-7.0: Triangle projectile attack.

New Features

• Added a triangle projectile attack. Starting at 4 points, triangles save the location of the player after colliding and attacking them, and fire, alongside other triangles, projectile, that deal 1 health point of damage at that location.

Improvements

• Player health has been increased from 10 to 15 to balance the effects of the new triangle projectile attack.
