The doom asteroid has hit! Run, jump, and claw your way to survival! The game can be played in CHALLENGE or SPEED RUN mode. It defaults to challenge, which is a collection of 7 levels. Speed runs can be unlocked and chosen in the OPTIONS screen. You need Bones to unlock speed runs (and buy goodies in the SHOP). You get bones by eating critters and reaching milestones. Use DNA to upgrade your dino, which is earned by collecting eggs and eating critters. The game is DEEP so EXPLORE and have fun!
