Edit: After reading the complete VN, it was fantastic. Indigo & Violetta were great characters with Violetta having good development, the world was interesting, the artwork is good & charming, and it's just a really nice read overall. 

My only criticism would be that the final action part with Violetta in the Purple ending felt it was lacking a lot of weight, especially since the big bad never got any dialogue. 

Overall, fantastic visual novel.

It's very promising so far, can't wait to see to see more of the story.
