Hey, finally got around to playing your game, folks!
I'm not a visual story kinda guy, just saying! So i don't really know tropes of the genre.
First off, the music and the art were great! The menu and UI are pretty good, i don't know if it's a premade engine or something you made yourself, anyways it's just overall good presentation.
As for the story, i wasn't very engaged by it, but to be honest romance stuff is not my thing to begin with! The choices felt a bit arbitrary as they mostly consisted of "say X or say X in a harsher, objecting way" though you'd eventually end up doing X anyways. Though i do believe the interactivity element was well used when signing off the letter when the different background came up! i think that was a good touch. Also i am a fan of big choices that leave an open ending, so that was cool too!
Overall, not my thing, but quite nice. Keep it up folks!
