Once you've worked your way through the aquarium and settled on a hiding place, time advances to night and the real game begins. After night begins, you almost immediately meet a helpful penguin who offers to help guide you to the exit. Shenanigans inevitably transpire and you end up blocked by something or other that needs you to do a fetch quest in order to get past each floor. None of the puzzles you're asked to solve …
