I loved the artstyle, it's the perfect mixture of cute and creepy (the Madoka inspiration is definitely there). I didn't expect the game to be this short though. As for the gameplay, it's simple but effective, although I would have loved to actually fight some enemies on the way.
How will Nadeshiko continue her duty as a magical girl?
PS: I got stuck for 10 minutes on the first screen because I forgot what a goldfinch was...
