Alrighty, I played the game! I must say, I loved it. Emi-chan was an excellent lead heroine and I loved her sarcasm. Contrast with Kou, it was just fun seeing the two banter. I only wish it was longer! Also, the proofreader inside me noticed some punctuation and a few grammar/spelling errors, but they weren't enough to be too distracting or take away from the story.
Now for spoiler related comments--
Her Mom was a monster! It's like she didn't care about Emi's mental state at all, whether she was happy. It caused Emi so much anxiety that the reason her art had no "soul" was because it must be perfect. This somewhat reminded me of Arima from "Your Lie In April" who was known as the Human Metronome. Perfect, but robotic. It seemed her dad was more caring... it didn't seem clear, but I am guessing they weren't together anymore or...? I have to say though, I feel that this part of the story felt a bit unresolved. She said she would come over and see the painting, so I am curious how she would have reacted if she saw the banner. There's so much that could be expanded upon here.
Oh, and with Kou's backstory... I love how Emi breaks the fourth wall and mentions "it was as if this scene existed for the rain in the title." Brilliant!
Overall, it was a cute story and I loved it! It made me laugh out loud (for real!) several time and smile. The dramatic bits felt real and you really care the more you learn about Emi and why she is the way she is. Gotta go back for the last CG and 3 more achievements, so far I got "Polkamon Master" wahaha loved that xD
