Unite as much as you can with under a single color. Then change it all arbitrarily to unite some more. This game look awfully like a political statement. Nice and very relaxing anyway. 4/5.
In the canopy forest, inside the tree: I took the star, the down-wall-jumped. A this point, the game became a grey screen. I was just wondering if it happened to anyone else. Otherwise, it's a truly great game.
