This was nice for a jam game, I mean, its literally 4 games in one, I understand this was rushed and appreciate the effort, and I liked it quite much, however, the racing game sucks that much that it affects the overall score, I loved the other 2 games nonetheless, maybe the DDR was too hard for me, but it was fun since you can't die xD.
The sprite work could be polished, Sumi looks so weird with her arms crossed xD.
But this is a fine concept and a good excuse to play a lot of touhou themed games, an expansion is something I would like to see.
