A lovely penguin Nick found while browsing the website that all penguins can't fly. Nick didn't believe this conclusion. He decided to study the principle of flight and do flight tests until he can fly successfully. Nick needs your help. Use hang gliding wings to make penguins fly. There is a red zone on each hang gliding wing, and the speed of reaching the red zone will continue to slow down, so you need to avoid reaching the red zone. It is worth noting that you can upgrade the fuel to make it faster! Launch the penguin as far as you can, can you get all the upgrades? You can unlock 4 new stages after you get certain achievements. Use left and right arrow to adjust your angle when flying.
