Click green flag, wait a second, and click it again. This is so that the lights work properly. Occasionally they work fine on one click, but usually two is necessary. Also, I'm still working on the ending--it doesn't work as planned.
Caution: Some sequences have flashing lights which may affect photosensitive viewers. There is a break in between the two acts, but don't go away. It only ends when the lights stop. Turn your volume very low, because the sound is already quite loud.
