I agree with JoseNt, there certainly are parts of the game that appear rough and unpolished, however, that doesn't stop it from being an admirable, albeit small, project. There is undeniable potential in this game, and if you ever feel up to the task, I know that I would be very interested in seeing this game expanded upon.
For such a short project, I admit that I was stunned by the pixel art of the backgrounds, However, the quality of the yokai seemed rather lackluster, especially Hayami. She has personality, but for what appears to be such a vital character in this game, her design does not stand out as much as I would have liked it to possess. That being said, the Tengu you meet at the beginning of the game in front of the castle is stunning. I would be very happy to see such quality expanded to the rest of the cast.
Overall, the game is short, sweet, and to the point. I adore the obvious Japanese influences in the narrative and would love to see this game fleshed out properly to make the story less choppy.
