A very calm, very chill game. I like pretty much everything about it, and everything is there to help you get into this "zen" zone - from animations to sfx and music. It's a very simple concept, but it's done beautifully, and it works. I absolutely love it.
If I were to complain about something - I guess it would be about items taking some time to get used to. But then again - it's pretty much a non-issue, and the tutorial definitely helps.
It's a great game, and an insta-buy for me when it releases.
