I recognized the visual style from The Karmic Scale, so I was very excited when I got to this one in the jam. I wasn't disappointed at all! The classic-style platformer plays relatively smoothly, with some fun extras to look for throughout the main level. The natural writing fits nicely as well, telling a cute short story with Reimu.
I did find fairies somewhat hard to hit due to Reimu's aim, and yellow bullets are especially hard to see in the open outdoor areas. Dialogues also don't stop fairy attacks, so it can be awkward to come out of them. Auto-pausing the game world in these moments might be a good fix.
Otherwise, you've done excellent work mitigating some troublesome gameplay moments. Infinite retries and a good use of checkpoints made sure that there weren't excessive setbacks - and allowed for very challenging but very fair encounters.On top of the good music, the visuals themselves are also colorful, shiny, and overall excellently presented. It shows a lot of personality, and I'm enjoying seeing the style develop. (The fumos help. :3 )
Overall, I can tell that your team put a lot of love into this, and it shows! Well done!
