Liked the first chapter, but was frustrated that there the transformation element was soon neglected. (I've seen this in Ranma 1/2 and Gatcha Gatch Secret, but my guess is the author ran out of ideas almost immediately after deciding to write a story about a girl who shifts forms. So we end up with a plot thread that just eats up virtual space since you keep wondering when there will be a shift, only it never happens.) Also the main character and her crush are boring people, and I stopped reading their conversations. The only thing that kept me reading to ch 20 was curiosity about the Goddess's slow as molasses relationship with someone that reminds me of CardCaptorSakura's brother. Yes they're both stock characters, but they're still funner to watch than the main story and it leaves you wondering if they should have been the focus of this work.
Overall its obvious the story could have been executed much better, and I saw a lot of missed chances for character elaboration or better drama...jokes for instance that only had two panels rather than 3 or more. There is also no antagonist and the series just limps along unsure of where its going...
In fact, I'm expecting a dreaded ending of the type where "the protagonist loses her memories of it all," to come any time now. Authors use it when they want drama, but are creatively bereft or have written themselves into a corner, and want to stop beating their head against the wall. They would rather reset everything at the end and make everything you read meaningless, than write a solution to the story. Also known as the screw-the-reader ending? I really wish Japanese authors didn't have a propensity for this type of ending, and Buddhism must be a deep influence. (I hope this direction isn't followed, but then again I never enjoyed Buddhist reincarnation in stories either, since if it doesn't allow you to keep your old memories, writing about a person's past is meaningless.) If I knew the author I'd try to convince him that this forshadowed ending is a lame cop-out, and ask him to please not give us a ending such as from the manga Karin.
The transitions were also pretty quick with sloppy time-skips, and more than once I had to stop reading to figure out where we were chronologically, or what just happened. I didn't care about most of the characters and the jokes stopped being as funny early on (I blame it on the lack of "follow-through" in the writing, although maybe it was also the translation.?) Add the fact that many characters are so simply differentiated that its easy to mix them up, and you have a recipe for confusion.
No transformation, suspicious foreshadowing of a crappy ending, light character development, and awkward transitions keep me from recommending this series to others. If you'd like to satisfy your curiousity just treat the 1st chapter as an interesting one-shot.
