The game is beautiful, great art style. Transition are very smooth, and everything is very relaxing.
The concept of having every level on a single map is very nice too.
Despite all that, the level doesn't seem to be finished. I got soft lock one of the last and the collisions got me on the wall. And every level seems to be very easy to go through.
Maybe next time you should add the tutorial in the end. I would prefer to have 2 levels well design even with a simple and overwhelming tutorial screen, than 6 tutorial level and no true level play.
Still, great job !
