Very relaxing and aesthetically pleasing of a game. Art is very polished, so as the overall 'vibe' of the environment.
It would be nice to have some of the game UI updated ( (one example is the text in the tutorial section of the game, it was offscreen when you play the browser version). Maybe it's more of a resolution problem. There's also the controls (though after a few minutes of gameplay, I got the hang of it), it can be quite hard to figure out at first.
But overall, a very good, short game, considering it was made in a week :) Awesome!
