Press H to hide the annoying fly that follows your mouse. Press S to show it again. Press L to land it on a blade of grass. Press space to make everything as it was before. Sometimes there will be a glitch or mess-up, please click the stop sign and then the flag to clear all of this. Easter eggs: Try pressing different letter keys or arrow keys! There's three... Showing and hiding (S and H keys) will NOT work with the landing fly or a special fly. Press space to make it normal, and then you can hide or show it. The special fly will not keep its color when landing.
