I love the game but it has a problem – NailCanvasLite -3DNailSimulator- Review

I will do one nail and it will flash out the game will go black and go back to my home screen and I loose my design I just did its aggravating And I wish you could pick your own color or mix them And it would be cool if you could choose where you want your design and how big or small you want it Other then that i love this app it's fun and Reilly cool. Hope you update it ?
