As part of the challenges I made to remake some famous projects and games, I tried to build my own version of Minecraft from scratch in a short period of time (~30 hours / 10 days).
This version of Minecraft was made using C++ and OpenGL without the use of any game engine.
This small project helps me learn and experiment with how game engines work, how math and physics work, how to solve some interesting problems, and how to solve them more quickly.
