For starters - yes, it is very short, for two evenings or maybe one intense night. But! It is also so frightening and gloomy, kind and sensitive and witty. You can really feel like a little child again for a while, when every shadow could be bogeyman, teddy bear was your biggest friend and your mommy was like a sun, center of your little universe. Ending is not fully surprising (if you pay attention during playing), but I will not say it is anticlimactic. It is meaningful, for story like this. I will certainly play it again after some time.
