🦒 Zoo Park Tycoon Simulator: 3D Main Menu, Build, Care, Research, Expand (Elephants, Big Cats, Savannah, Penguins, Tropical House, Aquarium, Reptiles, Butterflies)

Run a Blender-modelled 3D zoo park from a game-style main menu: eight habitats (elephants, big cats, savannah, penguins, glass tropical dome, aquarium, reptiles, butterfly garden), live money, feed, water, visitors and happiness. Animals eat by Kleiber's law (70 M^0.75 kcal/day), indoor habitats are held at set temperatures by a Newton-cooling HVAC model, visitors arrive by a price-dependent demand curve through an Erlang C ticket queue, and a price-sweep experiment finds the profit-maximising ticket price against the analytic optimum. Hire staff, research, build and expand, with nine in-page numerical checks.
