Technically, yes - there are a few. Siren Head can drop you to your death or, on occasion, slam you into the ground. If you press 'z' when the option comes up, Siren Head will crawl (very quickly) straight at you and kill you. Other ways to die are from fall damage from the ranger's tower, Lamp Head can crush you, and you die in the water if you touch it. But the main endings are finding that Siren Head got to the cops before you did, and giving up. But, we did recently get news that UndreamedPanic is going to further continue the story once she(?) addresses the bugs and issues.
