Very interesting game, I like all the custom art and the music is well implemented; the sound effects complimenting everything nicely.
It's an intriguing concept and I really liked what happens when (to try avoid spoilers) one of the puzzles is failed and everything goes to pieces.
It seems like puzzles are the main focus of the game and these are in large part well constructed and thought out. Unfortunately, I got stuck in one of the puzzles where you cannot retreat. Normally I try get past a puzzle but then go back and try something else when I cannot proceed but I was locked in and couldn't solve it so that's where my run ended (for now).
But great game - from the time I played it's very evident that you put a great amount of heart and soul into this and it's something to cherish and be proud of :)
P.S - Found one very small error. I know the game is being developed for English and Spanish players which I think is awesome. When asking Mason about information on the masks, one of the choices come up as 'Salir' instead of the English equivalent.
For the record, I played the English download version of this game.
