Nice game, I loved to make the colorful light rays snaking through every square of the game area. If only you could give us an option to admire the final arrangement a little bit more after completing the level... Maybe with a "next level" button flashing up somewhere on the bottom of the screen, which I can push after I'm finished with admiring the sight I worked so hard to achieve :)

 "Quantum Of Light"){kind=icon}
I'm glad you like the game :) Added a close button in the level complete screen - an option to admire the final arrangement (update 0.973)
