Both the cute cat style and the cat eared shop clerk style are incredibly adorable! Everyone keeps their cat traits, and the outfits, cat themed food, and even the UI are all cute, so I love absolutely everything, meow!!! The bonus hand drawn concept art felt like such a special reward.
I also looked at the concept art for Insomnia～不眠症～, and I really love your artwork, it is one of my favorites. It was an amazing game experience, thank you so much, meow!!! ฅ^•ﻌ•^ฅ
