I love this game. Thanks for creating and sharing your work! A slight issue I found, and I mean SLIGHT, is how the slower moving light trails can sometimes have big portions cut off by the "light gates"? "light doors"?... anyways. They'll get cut off and erased even after they have passed through the gates if there is still a portion that hasn't passed through yet. Either way it's practically a flawless game. I just thought that seemed like a bug. Great work!
