The story is rich, engaging, and richly layered, featuring complex characters, numerous plot twists, and a non-linear, mystery-driven narrative that keeps players invested. While the pacing can feel slow and overly dialogue-heavy, especially toward the end, the deep storytelling and immersive atmosphere are widely praised, making it the core strength of the game. However, its heavy focus on story over gameplay may not appeal to those seeking more action or faster progression.
- “I loved how the game encourages you to want to read all the dialogues to get more context for the story, which is not usual and has its depth.”
- “The story was very rich and complex, filled with sci-fi and backstory for each important character.”
- “This game's story is fantastic; it has so many twists and turns it's really hard to guess what's going to come next, but nothing comes off as forced or arbitrary.”
- “You are essentially playing a walking simulator to read more dialogue and story without any bosses at all until the very end of the game.”
- “Mainly wasn't a fan of having to spam talk to a bunch of NPCs till I figured out how to progress certain side missions.”
- “The gameplay is kinda harsh and I often got stuck in frame-perfect tutorial longer than the actual boss fights and the same applies for the plot too; if you didn't pay too much attention to their essays and discussions, you would be very confused about what is going on.”

The gameplay is engaging and challenging, featuring fun boss fights with intuitive mechanics and variable difficulty that reward learning and strategy. While the combat and puzzles are well-designed, gameplay segments are interspersed with lengthy story-driven cutscenes, leading to pacing issues for players who prefer more continuous action. Overall, the gameplay effectively complements the strong narrative and aesthetic, though it may feel sparse or slow for those seeking constant gameplay.
- “Very engaging story, battle gameplay is fun and difficult (get good!).”
- “There were a couple of fights I had to repeat multiple times, and never once did I feel like I was just bs'ing my way through, I was always catching onto mechanics intuitively over time.”
- “- Engaging boss fights and game mechanics, with variable difficulty based on your preferred playstyle.”
- “Especially towards the end of the game there is so much dialogue and little to no gameplay; if you prefer gameplay over story, this probably isn't for you.”
- “The gameplay is quite harsh, and I often got stuck in the frame-perfect tutorial longer than the actual boss fights. The plot was confusing if you didn't pay close attention to the extensive essays and discussions.”
- “The gameplay loop consists of 1-2 hours of cutscenes and story progression between each boss fight, with side content only accessible during breaks in the story.”

The game delivers a charming and emotionally engaging story with wholesome characters and world-building, though pacing between action sequences can feel slow.
