An excellent experience. This is a relatively short experience for anyone curious, essentially taking the form of a single dungeon with event battles scattered throughout. This isn't a "traditional" RPG where you grow over the course of the game, but essentially a game about puzzling your way through a variety of pressures using items and abilities granted to you from the beginning. So be aware of that. For what it's worth, I'd say that this makes it a lot easier to test whether you'll enjoy it than the average RPG might, so please try it out.
The battles are tied into the story, which is not so much a progression through events as a deep dive into one's history. This lets the work focus entirely on the specific story it wants to rather than trying to juggle too many balls, and the cutscenes are fairly poignant. My favorite is the one right after the maze, as it hits particularly hard as build-up to the climax.
Now, that said, the game is all about the fights and those cutscenes, so if you're looking for a sweeping game or aren't really that excited for puzzling out battles, you probably will not enjoy this game. It's active time battle as well, so if that pressures you too much, be warned. But as a small and well-crafted RPGMaker game, I definitely think it's worth trying before you decide whether you dislike it.
