No function to color in! – Drawerings - Mandala Kaleidoscope Drawings! Review

As far as I can tell, you can only draw lines for your mandala, not color in the resulting drawering. There's also no help system in app or on author's Web site. I can't believe they would make an app without this basic functionality. If I'm just missing something, please let me know and I'll remove this negative review.
