First of all, the story seems to targeted at children. I personally didn't find it interesting but I could see children liking this show. It's one of those shows that is not very memorable. You will probably forget about after a week. (I'm already forgetting things like 12 hours after watching this show)
The art work and animation is great but not on par with what Kyoani usually produces. I gave it an 8/10 because I feel like the art work and animation still outshines some of the TV anime in recent times. It's Kyoani, what else can I say :p
For sound, I honestly didn't remember any music; I know there are music but I cannot recall what they sound like. I do know it was fitting music so really no comments on this topic. The ending music is fairly cute though.
For characters, I really do like Baja, the main character. The way he/ she thinks really felt like he/ she is a newborn/ baby. Makes the character believable and real to me. The rest of the cast is not anything special though. Didn't make an impression on me through the 20-30mins.
Enjoyment wise, I didn't fall asleep. So that means it was at least an average for me. I wouldn't say I enjoyed it but I wouldn't say I hated it. Just average in my opinion.
Overall I gave it a 6/10 because I feel like this is has it's strong points considering it's 1 episode (20-30min), but the target audience is children and the story just isn't something I will want to watch again. Being made by Kyoani also bumped this show up a bit.
