A short and sweet game, I played 4 routes with all their endings so far, no issues whatsoever. The art style and character designs are great and fit the game perfectly.
My only nitpicks would be that I wish the actual routes were longer (I had a feeling there's a lot of backstory for each character we didn't get to learn) and the introduction could be a bit more elaborate (why we're dating, who the main character is, etc.).
Overall, an awesome job dev! Looking forward to more games from you! :-D
