My serious review is that I love the characterisation of Fin/Naoki's relationship from the dialogue alone, and the way you managed to imbue a house with so much personality is amazing! I love how the house's sass dropped some hints about where to go.
Cat's character designs are so good and the aesthetics were really beautiful and perfectly suited for the atmosphere you were creating. Awesome game design. Just really, really cool all around, please be proud of yourselves!
