|Collect toys and avoid normal and bigger baddies to pass to the next screen. Collect the keys to open a specific door (enlightened during the first 4 key sequences only). Time expiring takes away one life and the score is reset to how much it was in the beginning of the screen; also, any extra life in that screen is lost.|
Occasionally, some bonuses appear, it depends by how much time has been spent to unlock the doors or to take the keys, in different time ranges per level :
- Detonators: clear the screen from the normal baddies;
- PassPTouts: open all the doors;
- Klocks: close and lock all the doors;
- Klepsydras: give extra time.
At the end of any key sequence, just after the tenth screen in that row, secret bonus points levels appear, if Detonators and PassPTouts have been activated and collected in all the ten screens. If all the key sequences bonus level have been revealed, there's a secret final bonus points level, labeled 81.
After key sequence 4, in the last three screens (x8, x9, x0), opening a door when the time counter's last digit matches the last digit of the screen (e.g.: screen 68, time 38), Ghostmode is activated: Genius passes thru platforms and can't be killed for 10 seconds.
