# 2️⃣ Rank 02

- [so\_long](https://42-cursus.gitbook.io/guide/2-rank-02/so_long.md): The purpose of this project is to build a small 2D video game using MiniLibX and learn a bit about how a simple video game usually works.
- [Understand so\_long](https://42-cursus.gitbook.io/guide/2-rank-02/so_long/understand-so_long.md)
- [Core concepts](https://42-cursus.gitbook.io/guide/2-rank-02/so_long/core-concepts.md): I will describe some of the core concepts of making a simple video game

- [minitalk](https://42-cursus.gitbook.io/guide/2-rank-02/minitalk.md): The purpose of this project is to code a small data exchange program using UNIX signals. It is an introductory project for the bigger UNIX projects that will appear later on in the cursus.
- [Understand minitalk](https://42-cursus.gitbook.io/guide/2-rank-02/minitalk/understand-minitalk.md): You will have to realize a communication program in the form of a client and a server.
