Unexpected, just the way I like it. Beautiful, relaxing, and I wish it was longer. My only issue was (for me) I wish the movement was a little tighter. When I hit the arrow left or right, it moved way far. I would have preferred smaller increments of movement, as I would go all spazy, and have to reorient quite a bit. I got used to it but had to go slower.
Really fun game :) Got straight to the point and was very intuitive to me. Great concept overall and definitely one I'll remember.
Did I miss something? The game was completely devoid of substance. It was just "collect item, walk through door, repeat". No scares, no difficulty, nothing.
