I think this game is amaaaazing~! :D A great way to pass time, and beautiful music aswell. I love the pieces chosen for this game, I could play it for hours and hours. Granted a few of the puzzles stumped me - which is good, because after careful consideration, I was able to find a clever way through them. The difficulty is pretty nicely set - I'm sure about anyone would be able to do this, given the right amount of time to explain how the game works.
What else, what else? Ah - I'm not very sure. All I know is that this game, although simple in itself - is amazing to play~ I will definitely be back again on a night where I need time to pass :3 <3
