The initial few puzzles and text instruction need so e tweaking, they have obviously been translated and it's rather vague so I kind if had to figure it out myself, which I think I've done so, I'm at level 20 now, there's 100 altogether divided into four chapters.
There a various shapes of various colours placed over the screen, the aim is to make each side if the screen balanced, this done by tapping shapes which will then either swap colours with another shape or swap places with another shape, from what I can gather no two same colours can be on the same side of the screen. There's not much challenge to the levels I've played so far as the tap able areas are limited so there's not much chance of going wrong, however the game gives the impression it's gonna rank up a bit in the next chapter.
The music is japeneseish and adds to the tranquil style of the game, I'd say this probably won't appeal to the masses but if you enjoy kami, colour zen or harmony then you'll enjoy this, it's going alongside the other relaxing puzzlers for when I want to unwind.
I'll come back and edit once I figure out the rules for def.
