Yeah, it's using LineRenderer and then raycasting from an origin point until it hits a surface, adds the hit point to the LineRenderer's array of points, then figures out the reflection vector and does another raycast, and so on until the raycast doesn't hit anything and adds a point in that last direction off beyond the screen. I've never worked with raycasting before, so I'm learning something new!
One of the things I've learned from game jams is that it's a great way to identify what types of reusable systems you might want to create so it's easy to drag and drop things into future games. Some examples for me are overlays that fade in and out on command and audio sources with additional controls like fading out when switching to another background song. I made all those manually this time, but I'd love to get them into my Unity utils repo and done well so I can easily make use of them in the future!
Thanks for playing! If it's touchy, make sure to use the Shift+Space or W+S gamepad buttons together to move extra slow. I added that because it's hard to bend the light accurately after bouncing it a few times off of surfaces. :)
