Oh my god. I can't even express how good this game was—but I'm going to try. Prepare yourself...
Let's ignore the emotional story for now and start with the gameplay and mechanics. This game gave me the same addictive dopamine rush I got from Witcher 3's Gwent. And I really loved Gwent; at least 90% of my hours in Witcher 3 were spent on it. For me, this game has the same vibes, and if it ever came out as a finalized product, I'd be hooked for life.
The animations, the animated text, every little detail, and the fact that nothing on the screen was ever really still made this game look so complete it feels like it took months to develop. I'm so impressed with the amount of work you put into this and I can't come up with a single negative thing to say about the game.
As for the story, I'm not sure if it was personal, but it sure felt like it. Personal or not, the message was important, and I hope anyone struggling with the topics represented in this game, or any mental health issues, finds peace and happiness in their life. The dialogue, or rather monologue, reminded me of Celeste, with all of the emotion expressed just through the sound effects and the speed of the text—they drastically added to the overall feeling of this game. The story was well-crafted from start to finish, and the "reboot" was a cool transition to the endgame.
The ending of this game was amazing. I obviously wish it was longer, but I do think it needed to end where it did. I liked the small detail where you had to deal 6 damage to the ???. I also especially loved the fact that the game closes when you finish it. It really felt like you told me a story, ended it with "That's it, there's nothing else left to say," closed the book on my face, and left me wanting for more. I don't know how this game only has 16 ratings as I'm writing this; it's truly a hidden gem.
TLDR: The game was good. Play it.
