I was immediately impressed with the music and visuals! It's always fun to see the Touhou characters in 3D like this, and the tracks from prior jams and those made for this one both complemented the racing really well. The wall screeching sound is okay; how else would car manufacturers discourage people grinding against walls for the thrill? :3
I did notice some jam jank with the objectives not always being marked as cleared, which made it hard to progress - although I did enjoy going through the tracks! They have a good amount of variance, and the challenge is definitely front-and-center.
The writing was also a fun addition, although I would have been curious about how it finished out after clearing the rest of the story objectives.
In any case, the game's concept overall was really interesting, and I had quite a lot of fun! Well done as always!
