I wanna say first that the one preview there with the battle UI made me think there was a turn-based-battle thing at some point, but the page does say "Visual Novel made with Ren'py" so thats my bad. Its just a visual thing for a couple scenes so nothing big.
The game itself was very good though. Lucy's anxiety and slightly-autistic personality made her very relatable and the overall story of her getting a small bit of confidence was encouraging. Characters are cute and the third act even has a bit of tension behind it so I'd definitely say its worth the 5 bucks
