I think the quiz answers are bugged. Citizen Kane didn't work, but just pressing the first answer for all three movie selections did work.
Also, Takua/George's script isn't properly textured. It's blank. And when I try to talk to him in Level 3 (using the Level Select feature), his text box just says "Tohunga".
And I can't find the coffee cups. I guess maybe that's supposed to be unlocked by asking everyone about coffee but getting to the mocha guy is practically impossible. There should be a flight mode or a low gravity mode to help with all of the physics puzzles.
Honestly, these are all issues I could probably fix myself if I had the project files.
