I've got to the end of this game 3 times and tried to put the code in with no success. It's quite irritating that I'm having my time wasted due to a small bug, I really hope the issue is fixed soon.
I noticed a pattern in the number of floors. The number of floor above is the number or the floor below added twice and the number below that umber taken away.
these crazy grinns have their way...it boggles our minds too :P
