The 2D astronaut starts the first level in Detroit as Grand Circus’s mascot Grant Chirpus. Grant makes his way to a portal that launches him into space. Each level gets increasingly more difficult until he reaches level 5 and must face the boss. This game is optimized for mobile. Tilting moves AstroG left or right and tapping makes him jump.
