All files have been updated and confirmed to work with LOVE2D version 11.3 as of 6.22.2020. Main updates:

• file push.lua v0.2 updated to v0.4
• updated RBGA format updated from range 0-255 to range 0.00-1.00 (retained original colors selection).
• fixed majority of Ball.lua files having dx/dy (delta x, delta y) swapped - causing initial ball acceleration in the y axis (going up or down instead of to the sides)
