I never got around to finishing this project, but it was a great learning experience, especially when it comes to creating custom editor tools in Unity.
A 3D endless runner game built in Unity, with a focus on custom editor tooling. The gameplay loop is simple: avoid obstacles and collect coins as the level scrolls forward. What made this project interesting was building the level editor tools inside the Unity Editor itself — tools for platform placement, slicing, combining, and spread generation.
