Rocket vs Alien Swarm
Initial prompt
let's have a rocket in space. Let the aliens attack this rocket. And let the rocket shoot at these aliens. for every alien who touches the rocket, let the rocket's life decrease. And for every alien hit by the rocket, let the rocket's level rise. Let the aliens disappear in 2 strokes. An increase in the level 7 of the rocket alien.
