@Alvare: I wouldn’t put any concept of “damage” or “health” in the game, because the game is not about a character with “N lives”, but about the experience at liminal spaces. It’s true that it looks unrealistic to fall and not lose health, but if you had to be careful of not losing all the health, the gameplay would be completely different, and it wouldn’t have much to do with liminal spaces.
I like however that the encounter with the mysterious character teleports you to the beginning of that level (as it happens now, in the men showers)
