Interesting and cool game :) I felt that the ray could have been limited in lenght to avoid the "discotheque" effect when inside a circle, which for me breaks a little bit the relaxing mood.
I was trying to find a way to not make it bounce around so energetically, but I actually quite like the discotheque vibe in the circles :p I'll experiment more with the ray length, though. I think there's a happy medium! Thanks for playing :D
