KOURO

A puzzle game where light enters from somewhere on the screen, bounces and bends off objects like mirrors and glass, and you have to figure out where it exits!

You get guide lines up to the first object, but after that, you're on your own—estimating the path based on object shapes and refractive indices. Everything is calculated using real-world physics (no luck involved!), and puzzles are procedurally generated every time you play.

There's also a creative mode, allowing you to share or play the same stages using level codes with your friends!
