The thing I spend the most time on was the sled movement, ensuring that players could navigate the slopes with precision and skill. This involved fine-tuning and bending the physics to get the perfect balance between realism and fun, allowing for a thrilling and immersive gameplay experience. 

I made a system that randomly spawns the obstacles on the slope. So each run would be a new challenge. I also worked on a split-screen feature, allowing for local multiplayer gameplay that added an extra layer of excitement and competition. By implementing rag doll physics, it added a touch of humour to the game's crashes.
