Ooh, I like text adventures! The concept is pretty interesting, and the character concept art you showed in the game's description looks great.
The premise of trying to solve a case through dating rather than investigation and interrogation is fun. But to me, the dates didn't quite feel like actual dates, and I felt that the characters' personalities didn't come through as well in writing as they did in the illustrations.
I ended up guessing the Grandma as the culprit, which turned out to be wrong. The game mentioned that the public was dissatisfied with the show, but never explained why. I think that could be a good way to give the player hints about what they missed and encourage them to try again.
I like that you decided to revive an old idea you never had the opportunity to make, and I think the core concept is very interesting. I'd love to see the writing developed further to make the most of it.
Thank you for sharing your game!
