Allright... I'll give a honest feedback.
First of all... what mobile you use for testing? I checked ot out with SGS4 and it is unfortunately laggy - but playable. However I see your min Android requirement is 4.0. I suggest to change it ti minimum 4.4 once Intel fix the issue with API.
Now regarding the ge itself. I am really not fan of adventure games but I played several. Yours looks very pleasant. The problem is that the intro is way too long IMO. Trailer is also way to long.
And I stucked at the very beginning of the game once I jumped into the box. Had no idea what to do next.
And everytime I touched the sign I had the same text. To me it looked like a bug.
Again I'm not a fan of adventure games so I'm not an expert. Maybe that's the way it should be;) but consider addind some poping up tips if player stuck somewere for X time - at least at the beginning of the game.
But the overall looks really nice, and as I said before I love games made of free assets. The free characters are like the movie stars... you see the same face, but it's a different movie and you're curious what role will he play now!? ;D
