There's a lot to enjoy about this!
The gameplay is very responsive and flows well. The only issue that I found was the lack of a dialogue back button. Unity's constraints often result in mute-on-alt-tab games, meaning that it's easy for the likes of me to accidentally click through something while trying to refocus the game on the browser. If there was a back button, or at least a specific button+hotkey to advance dialogue, that could solve these issues.
I haven't seen much quite like this concept before. It's simple and follows a formula, but it's innovative and unique in its own little way!
The art has been improving a lot, too! It's gotten quite clean and colorful, and fills the scene out nicely. No notes; everything is excellent to look at. *u*
The music has some fun remixes to listen to, while also listening to the conversations. Speaking of which, the conversations are very delightful and feel very natural!
The balance also fairly challenges the player to find the perfect matches in a perfect exploration of romance (and lack thereof). Even if there's only one day in the demo, it's overall a very fun experience to get this kind of time with the characters. Well done!
