(YOUR GAME IS FIRST IN THE VIDEO)
So, first of all - this is not an uninteresting game. There are some eerie moments, and the idea of starting out because you react to the crying and implied abuse is a fine enough motivation. And especially the ending has a very striking visual that I really like.
However, you may want to either rework things or rethink calling your demos a "Playable Teaser". Regardless of how good the game is, you do little other than set yourself up for unfavorable comparisons, which is not fair to your own work. At least, these are my personal thoughts on the PT-style games. And I have to join the choir on the slow walking speed - it's more irritating than creepy.
I repeat, this is not bad at all, there's very solid work here, but this teaser tells me nothing about your game, what to expect from it or how it differs from anything else.
