realized mini-game
A lot of basic math plus logic was used.
The functions that the current engine does not have are all added by Cherno in the game, such as particles and collisions.

- I want to turn Hazel into a real game engine, which has a graphical interface, and can easily and quickly develop games like flybird
- From the development of the small game in Section 059, reverse engineering should be used to move the functions of this small game to Hazel, including collision, particles, and GUI
- Optimize the code of the 2D rendering API to achieve batch rendering .
