Moon lander

a 2D game of gravity using SDL3 / Pascal

This is my attempt to bring "moon lander" back to life.
This version of Moonlander is almost rewritten from scratch, using Pascal and SDL3.

Dependencies

Windows and Linux:

• sdl3

• sdl3-image

• sdl3-mixer

• JsonTools

• Lazarus / Freepascal

• Pascal SDL3 Header files 

  [https://github.com/sechshelme/Lazarus-SDL-3.0-Packages-and-Examples](https://github.com/sechshelme/Lazarus-SDL-3.0-Packages-and-Examples)

  [https://github.com/PascalGameDevelopment/SDL3-for-Pascal](https://github.com/PascalGameDevelopment/SDL3-for-Pascal)

a good installation guide for SDL3 can be found at: [https://www.freepascal-meets-sdl.net/](https://www.freepascal-meets-sdl.net/)

Why ?

I want to learn how to use SDL3 to get easy acess to graphic, sound and input.
