Most of the game was pretty spooky--and the "swarm" actually did rather get me! ^_^

That said, the "puzzle" segment felt more frustrating and tiresome than scary, to me: It took me a while to discover what it was that I was supposed to be taking note of, and once I did, the filters between "stages" were, to me, just annoying. :/

You did give warning about flashing lights, but wow, those were rather unpleasant. :/

However, those were two brief sections of what was otherwise a nicely eerie, ambiguous piece of horror, with a good sense of tension. ^_^
