Gah! It started out so good! Got stinking sappy. Started to get good again and then fell into a pit of so much sappiness that I couldn't wait to get out of it!
OK it wasn't THAT bad. The story was charming, the tone was light, the animation was decent if not amazing, the music was worth listening to. I felt like they could have made it in 20 episodes and it would have been far better. Just cut some of the crap out. It fell into some tropes like the harem and other things but it turned out decently.
If you want a darker tone go with Re: Zero
If you want a more fun happy skippy jumpy plot that is better done: That Time I was reincarnated as a Slime.
