One more game to demonstrate that telling stories without hurting interactivity (which lenghty non-interactive cinematics usually do) is entirely possible, if not much more powerful.
Here the non-litteral story is distilled progressively through various clues: short dreams allusion, characters relationship and interactions and a few metaphors. It just works.

As for the actual gameplay, this is a kind of ICO-like gameplay, using different mechamisms (with the usual switches, levers and the like...)
The nicest thing about almost all puzzles is the ability to manipulate the scenery, which is almost a living thing.

This game is short (3~4 hours, more if you want to collect stuff), which is not a problem afaic, because why should story-focused games *need* 40 hours to tell a simple story ? Ihmo this game is no shorter nor longer that it should be, but, most importantly, the story ends in a logical but not quite expected way you will not easily forget.
