I've gotta say, Neverending Light is one of the best flash thriller games I've ever played.
It's the type of game that isn't so scary that it becomes cheesy, but just scary enough to creep you out, yet pull you into the game even more at the same time.
I cannot wait for the next game in the series, especially after reading the spoilers from collecting all the sprite droppings.
It's good, the only flaw is that there is no health, so you know you can't die even though a monster bites you 25000 times. That's what I hate about it.
