I really liked this!! The clowns were faster to wake up than I thought, which gave me quite a fright on a few levels. A little detail I noticed which doesn't detract from gameplay is that once you die, in that window of time before the retry screen you can still expand your light, which is funny.
One little thing to consider is that after you die if there were too many clowns the volume is real high and it keeps going before the retry screen comes up.
