Art style is adorable, however as Ferdy said it's a little rough. Think music could improve the experience quite a bit, but I think the sound effects are charming enough. Really enjoyed the minigames.
Also, is it a bug that after completing Snowboarding and then Snowball Fighting you can buy not only Joon's and Kosuzu's item, but also Rinnosuke?

We didn't have anyone working with audio on our team so we tried to use sound effects to have some audio experience, we will try our best to deliver a game with full audio experience next time!
Rinnosuke is supposed to be unlocked only after getting 2000 score in Dress-Up Jorge, we will look into it thanks for the feedback!
