Thanks for your helpful comment. I glad you like it. The max number of bounces was 20, I didn't think it was an issue at first. But I think rising them to 10000 would be a lot of fun.
I was late for the submission so the Lazer was a bit buggy. The edge of the mirror was intended for spitting into 2 Lazer for more end point . But I don't have enough time so there was no simple case level .
