Your mission has brought you to an immense labyrinth where you must gather precious crystals. What was supposed to be an easy assignment, quickly changes when gigantic space eels awaken and want to make you their next meal!

Crystal Chompers was developed as part of a suite of cognitive games, aimed at supporting Brain Health. This game focuses on challenging divided attention. We humans all have a finite amount of attentional resources. Adding new tasks that must be handled simultaneously with other tasks, reduces the amount of attention that can be devoted to each individual task. How much can you handle?
