Well for keypad enter the 3 digits from the piece of paper (near plant) and then 3 digit of how long it takes earth to orbit the sun (which equates to a year)
The only way to progress in this game is to go at max or just below speed and randomly jump on the boxes. And even if you can read 3 to 6 line verse in 4 seconds while navigating the impossible boxes it will take you well over 24 hours to complete the game with no reward I would imagine. Unless you're life is devoted to Finnish Epic Poetry. Waste of time, no save game, not fun, nuf sed.
