456 impostor

Astronaut #456 is attempting to remain alive in the vastness of space. The only way to progress is by defeating the enemies in red uniforms, requiring you to jump on top of them and crush them. Doing so will allow you to advance to the next level. Notably, every 10 levels a 'endless run' mode is triggered, accompanied by the same enemy type that must be eliminated. Game Instructions: WASD keys + Mobile touch controls.
