for those who are confused:
Click where you want Eggdog to go, hold for how far he goes in that direction. while playing, r to restart and esc to escape back to the main menu. while in the main menu, rub your mouse back and forth over Eggdog to pet Eggdog, or drag eggdog to throw him around. besides that, onscreen buttons do what they do. don't press esc on the main menu, that hard-locks the game. if the music doesn't exist in the main menu at first, click once to start it.
