The mod adds a small element of realism to the game - butterflies, midges, bugs and other insects flying around the city.
The script is based on developments from Overdose Effects, but as far as I know, butterflies and midges were found there only in specific places (like the original flies, they were most likely only near garbage cans), but they did not fly anywhere in the city. With this mod, they will fly just the same around the city.
With effects Overdose Effectshad to face while making effects for the autumn mod Autumn Sunshine, and then we came up with the idea to use them to spice up the summer mod as well, so we can say that this mod is a small addition to Endless Summer, but it can be freely installed on a clean game.
