This was cute (and almost as retro as you can get in terms of games as a medium lol). Very funny idea to adapt Touhou to the beginnings of the genre.
The sound effects were a bit jarring for me sometimes. It seems that the same sound can play twice at the same time. Which will just effectively increase the volume if they're coming from the same "source."
While the jam version is only one stage, was still cool that there are three scenarios/characters.
