This is incredible to see a creation of this caliber at a game jam. It really shows that everybody on your team has given it their all. Sound is great and immersive, controls are really smooth and intuitive, the story is interesting, and the art is just 10/10.
The only minus I could mention isn't even objective. The character in the corner was quite distracting to me personally. My eyes were drawn to her, and focusing on what's behind was tough. I would appreciate it if she didn't just sit there with me, but had a separate little window with less saturation so I could drown her out while navigating the surroundings.
Other than that, the game was great! Had me on the edge of my seat from the very start, and I would love to see it develop further.
