First of all, it's short, really short, too short, the characters have potential and are drawn nicely (backgrounds are quite nice too), but most remain shallow, the only character one gets to know a bit more is Jennie, the Wishmaster, but Undine and Momo have too less dialogue to get to know the friend and the witch. That combined with at least one spelling error (ar instead of are) and a quite hard to see title menu, makes it in my opinion a C+ (hopefully translating the 3+ from our school system [1 best possible, 4 enough to pass, 6 worst possible] correctly) only, it's all in all over average but sadly leaves way too much potential open.
Critic points: too short for character depth, at least one (i noticed in the first playthrough) minor spelling error, title menu hardly readable
