The title screen grabbed me right away, and the whole psychic-unveiling mechanic is such a sick idea, using it to reveal hazards, key items, and seeing all the little hints felt really satisfying. The audio design is a big highlight too: the SFX are super nice (unlocking floors /finding key items is especially satisfying), and the music has that chill-but-mysterious vibe that fits the abandoned building perfectly. The visuals are top-notch as well.
Also, the little details you hide behind the unveil are great. The pictures on the walls turning into eyeballs were really unsettling lol. Really cool concept, presentation, and especially a really good first game jam entry.
