Just 100% completed this game. I'd voted for it on Greenlight a while back, and a week ago I went to check if any of the games I voted for had been greenlit, and saw that this game was out! Shame that I somehow missed the news when it came out.
Extremely minor spoilers below, I suppose:
I love it. This is one of my favorite games I've played in a while. I think the visuals, audio, ambiance, and most importantly gameplay are just wonderful. It manages to both successfully recreate the important aspects of Link's Awakening, and at the same time feel completely fresh. I've never played Fez, but from what I hear, the first half of the game is a simple-ish platformer, and the second half is where the real fun starts. That's exactly how this game felt. Except that the first "traditional" half is just a great game by itself; I had no idea that the second half was coming, and it's a gameplay mechanic that's executed perfectly, and that feels like nothing else I've done in any game. I was a bit disappointed that there was no big payoff or anything for completing all the post-game stuff, but the journey itself was enjoyable enough in and of itself. Extremely impressed that two guys could pull this off, and am looking forward to what they do next! Everyone must check this game out!
