This was overall a sweet game. The story was nice, the characters were likable, and the message was positive. The art worked well together and I liked the use of light and dark in to show the same image differently.
The mini game puzzles were a nice addition. It took a little bit at first to realize the current color was randomly selected between the three options and that I could click on the same a circle that I had already put a color if I didn't need any more, but once I figure that out I didn't have any troubles. I liked that you included the name of each color after you placed it, though I think it would have been beneficial if you had included the name beforehand, either as text on the circle of light itself or text under it or something similar.
Some of the text under Preferences, About, and Help was a little hard to read against the title screen.. It was much easier to read the text when pausing and going to those options while playing the game itself, due to the darker background.
All in all, this was a nice game with a enjoyable story.
