ASTRO STOMP

Move: arrow keys or A/D   Jump: space, up or W   Smash: down or S while in the air   Fullscreen: F
Cross Mars, Venus and Saturn and reach the rocket on each. Smash aliens from above; touching them, their shots or a hazard costs oxygen. Every alien has a trick: stalkers pounce, blades throw discs, brutes take three smashes and send out shock waves (jump them), ravagers charge and get dazed if they hit a wall, brains fire orbs and flies dive or drip acid. Watch out for cliffs, low cave roofs, falling rocks, crushers, lava geysers and lasers. Grab O2 tanks for extra oxygen and touch the flag for a checkpoint. Run out of oxygen and you get a free refill.
