WOW....
This is the first time I have really looked into the "Colour" series, but I must say, I love it! There were a few things I noticed after I went and played the other games as well as this one.... first, this one WAS harder than your others. Took me awhile to find everything, but that made it more interesting!
One note I had....
The big lift to get to the top of the tree? I wasnt on it when I pressed the lever. There's no way to get it back down after you press it if you're not on it!
That's really my only note, but please continue the series! The artwork is beautiful, and I love how your stories revolve around love and creativity.
