I adored this game. The art and animation was over the top in the best ways possible. The only actual issue I had was the strange disconect in the music. Some of it was classical stuff where you could even hear the snap and pop of a record, while over tracks were 16 bit video game stuff. It works, but it's still odd enough to confuse me. The lack of any voice acting or text blurbs was also a bit lack luster at first, although the audio that was present was used well. There were also a few lines that with japanese phrases that I wasn't familiar with and had to look up to understand, as well as a few moment where I wasn't entirely sure what I was looking at until it was explained several sentences in after it showed up, but those are minor complaints at best.
Over all the game's art and animation steal the show. There are so many fun references hidden in the backgrounds, the art is beautiful and sheer amount and quality of the animations and CG's put many big budget Visual Novels to shame. The choice to work in black and white not only allowed for a distinctive style in the jam but allowed for some much detail and creativity. While the lack of voice acting in a jam with pushes for voice actors is a strike against it, the decision to devote the time it would take to other aspects of the game paid off in spades! If this doesn't make the top three at least I will be very surprised.
