Use the arrow keys or I J K L to move the arrow and get as many of the RIGHT crystals before the time runs out. But beware, some of the crystals are fake and will send you back to start (don't touch the green either). But just your luck, the arrow always points to the right one. (If retrying the game make sure to press the green flag twice) make sure to Heart and fave!!
Tip: When boost meter is full use W A S D to boost in desired direction moving you over an extra space and jumping any THIN wall. Note: The more points you score the more the area changes! (Hey you, yes you, if you get past 4000 points you get a secret Easter egg!) Comment if you got the Easter egg!!!
