The art style of the game is very cute, the game is still a bit rough. For some reason I can't seem to complete the story, For some reason, I can't buy Kosuzu's item, it's sold out when I completed the minigame, but I was able to buy everything from the other stalls...

It is a known bug that will be fixed after the Jam, you have to buy snowboard item (Mochi) first to avoid it.... I will write that down in the page thanks for reminding me! The only way to fix it is by updating the page and trying again... But thanks for the feedback, hopefully you will be able to complete the game with no issues next time!
