Abyss School

Abyss School follows Yuhee, an ordinary girl who attends a private school. After finding a bright purple conch shell on the beach, she falls asleep from unbearable drowsiness on her school bus. When she wakes, her school has sunk into the deep sea, where followers gather around a high priest.

You solve puzzles set by the Abyss Followers, search for hidden items and avoid abyss zombies, terrible monsters and traps as you try to escape the school and return to your original world. Skins and cutscenes unlock as you play.
