I challenged myself to make a simple 3D voxel platformer in a week from scratch in C++. I reused a small amount of code from my previous voxel experiments (the meshing algorithm and the Qubicle file parser). I made all of the assets myself (programmer art (;). The external dependencies I used were GLEW, for loading OpenGL extensions, GLFW for cross-platform windows and input and GLM for math.
You can see the source code or download a release in the game’s github repository.
