Lovely! I liked that the game comprised three separate stories. The chocolates and hat episodes had really cute plots and good humour; finding the hat was harder than I expected, but I managed to do it in the end! Also, I half expected Ichirin to get accustomed to sweet flavours and end up not liking Futo's chocolates, but your version is much more adorable.
I really appreciated that the third episode was mostly centered around gameplay, it was a nice change of pace! The Touhou spin on "Uno" was quite simple, but I especially liked the feng shui mechanic that let you change colours every once in a while, as I'm sure it could have become a slog without it. That was good intuition! The game glitched during the final showdown, but I won anyway, and it only happened once. It was nothing serious though, I'm sure you could have made some adjustments if you had had a bit more time!
I don't think I know of any other game with a theme song! And the art was cute all around! Overall, I really liked it, and I could see that you all made a ton of effort to bring us this game in just two weeks. Thank you!
