if you is underground, left click, and the ant will follow the mouse, if you is in the surfice, controll with the arrows, and press down to go to the underground again.
Maybe later i'll add a npc to get leaves with you if you'r not in the main area. Oh! This is my first project! The code is soo funky xD it's good to remeber the old times =] Please ignore the portuguese variables xD
