This was an engaging visual novel. The story was quite compelling, and I think the animated scenes and the effectiveness of the sound effects added a lot to the experience. I think my main comment is pretty inconsequential, but I think the music was good, but felt a little out of place right after the fight. Since they just beat all the Shades, I thought that the music would be a bit more triumphant, and then once Stephanie realized she'd have to change back again, and in front of the other two magical girls, it was going to switch to the more somber soundtrack.
Also, the "Wynn?" to "Nguyen" was a good one. I was very confused when I first saw it, but once I connected the dots it gave me a good chuckle.
