GAME MODES TO TEST YOUR REFLEXES

CLASSIC MODE: The Endless Climb

Master the physics of the bounce! Perfect your timing on shifting platforms that shrink as you climb higher. It’s you versus gravity in a peaceful yet increasingly tense ascent to the stars.

FLOOR IS LAVA MODE: Beat the Heat! Unlocked at 500m in Classic.

Speed is life! Searing, glowing lava is rising from the depths, and it scales in speed the higher you go. Make split-second decisions, find the optimal route, and climb fast or get toasted!

SWARM MODE: Dodge the Critters! Unlocked at 700m in Lava.

The sky is falling! Navigate a treacherous obstacle course while dodging a descending, wiggling swarm of hostile bugs. Keep your head on a swivel!

BOSS BATTLE: Defeat the Bug King! Unlocked at 550m in Swarm.

Face off against the insect monarch himself! The Bug King reigns at the top of the vertical frontier. Dodge his wiggling minions, time your landing on heavy Cannon Platforms, and fire explosive cannonballs to blast the King out of the sky!
