I was interested when I read that this game implements a unique concept of recording existing dialogue in order to talk to characters and progress in the story. It's a very short game, so my main impression of it was that it's an fun concept that's sort of like a puzzle game. The development team introduced this mechanic fairly well through the story dialogue and a simple user interface.
The writer(s) did a good job with the dialogue to introduce the characters (and plants!), give hints about your objective, and allude to the world at large. When I'm on a tiny floating island and the villagers (plants!) discuss "world down there", and their strange sounding cities, I feel immersed in this fantastical world. What does a world look like where plants get along as humans do? It definitely piques my interest in what could come next in the story.
Overall, Hazel the Plant Witch tells a pleasant and short story that makes you want to know more about the world where plants can communicate. The dialogue recording concept is refreshing, and the writing is solid.
