Ok, One of your better games. There were only two things that turned out to be completely illogical. 1 was the thing you had to do with the egg, and the other was how to get the the thing in the air. For the second, I would have placed an H landing zone toy somewhere on the ground -- or be able to launch directly out of inventory.
For the first, Perhaps a chicken is more obvious than a monkey.
Absolutely impossible without the walkthrough. I could get half the puzzles, but the arbitrary clock codes sprinkled around and the 105 code were just random.
