• This game uses an internal timer. You must complete the game, collect every treasure, and allow your final time to be displayed for your score to count. 

• You are allowed to backtrack to previous areas, since whenever the game auto-saves between stages it also saves your total time. 

• You are allowed to take a brief break to rest your eyes between stages if you want to, but you cannot pause the game to do so. It must be done on the save screen between stages and cannot be for  longer than 30 seconds.
