Crystal Descent
Crystal Descent sends a fish swimming down a crystal cave. Grab gems, dodge sharks, jellyfish and eels, and answer a question at every checkpoint.
The demo needs no account and no card.
About Crystal Descent
The deeper you go, the more there is to dodge, so the checkpoints double as a breather. The cave changes as you sink, from crystal shallows through a kelp forest and coral ruins to a pitch-dark abyss, and no two dives lay out the same way.
Your answers shape the dive: a right answer heals a heart and powers up the next stretch with a gem magnet, a shield bubble or a gem surge, while a miss makes the water murky and resets your combo.
It plays both multiple-choice and matching questions.

What do I avoid in Crystal Descent?
Sharks, jellyfish, eels, urchins and rocks, plus pufferfish and anglerfish deeper down. Gems along the way are worth grabbing.
