I will have to come back to this not on my lunch break with only a trackpad on my work laptop because the scrolling is near impossible with that. It seemed like the 3rd shape that was broken up, the triangle on the left side did not fit with the other pieces but it could be I kept scrolling past the correct size. It was nice that the other 2 pieces gave an audio queue that they were in the right spot. Reminded me of the puzzle pieces in Braid. Very nice clean design from all members of the team. As a fellow audio maker, Kim Tae Woo's sounds were well done.
