### Things to consider:
|
|
# Event timer and gravities: somehow, not all gravities work for sprite to be killed when specified within loop, but I am unable to understand why. The following are pairs that work: (5:2500,5000), (1:500,1000), (2:2000,4000).
|
|
# A list of other nice RGB colors that can be used in the background: rgb(165,113,100) rgb(176, 155, 113) rgb(173, 139, 115) rgb(112, 79, 79) rgb(92, 61, 46)

# Apr 13th 2024. Changed pygame.time.set_timer(LEAF1, 500) to pygame.time.set_timer(LEAF1, 1200) and also clock tick from 40 to 30. also added line pygame.mixer.pre_init(44100, 16, 2, 4096)
