Absolutely fabulous!
Yes, First place without a doubt. There are so many projects which inspire in this game jam. But yours is special. Perfect visual with good optimization (punch myself, huh), real good sound desin. Music creeping me out, but in the time calming me too and helping thinking. But what realy inportant - flow state. Real flow state like in a big games from big boys. Puzzles are perfect, not to hard, but no brainless. And you feel like you can do anything even if you know game is linear. Process like in our favorite oldschool horrors (Sh, Re, Condemned etc).
But... Just... One... Thing:) Clock puzzles. It was very hard. First time when I used walktrough. Ok, UV on paintig - good. But another clock - I don't get it:) But everything else - gorgeous! Thanks for good time. Make some details - and go to Steam or another shop:)
P.s. Did you ever read something about gamedesign? I realy want to know!
