This is a simple game where you play as a bouncy square rock that has a grappling hook. It can use the grappling hook to swing to the end of the cave. There is no reward for doing so, but there is a timer.
### Description and Features
- Entirely written in C using only the SDL2 graphics and audio libraries.
- Procedurally generated cave environment using a random walk and procedurally
generated colour palettes.
- Cute synthesized sound effects using integer overflow a la [bytebeat](https://arxiv.org/pdf/1112.1368.pdf).
- 2D Graphics using the SDL2 API, no assets are used aside from the font.
- Point mass elastic physics with elastic collisions.
- Separating Axis Theorem collision test for convex polygons.
- Framerate independent physics uses a fixed timestep and completes as many
steps as neccessary to catch up to each frame.
- Physics runs in a separate thread and state is managed using shared memory and
locks.
- Player physics interactions use forces applied to physics bodies which are
