This looks like a niche visual novel/game that will probably appeal to players who enjoy story-driven experiences with unique gameplay mechanics. For games in this category, the quality of the writing, character development, and player choices usually have a much bigger impact on the overall experience than the concept alone.
Before downloading, I'd recommend checking user reviews, gameplay videos, and compatibility information to make sure the game runs properly on your device and offers the features you're looking for. A well-designed interface, stable performance, and engaging progression system can make a huge difference in how enjoyable the game feels over time.
