Highly enjoyable but gets quite hard at some point, I love to see that someone has actually gamificied character customization! I was so proud of myself every time I realized what they wanted. Also, the art is cute.
At what point in the game did you find it difficult? I've noticed that it varies from person to person. The game originally had no hints at all, so I'm glad I added them...
I managed the first two without hints, then finished the third level but got stuck with the fourth one. But I'm also not sure if the missions were too hard for real or if I was just too tired to think :D
