"Something about rockets that shrink planets!" (naming things is hard!) is my entry for LD38, it's a top down shoter thingy, where you have to protect your home planet from incoming aliens / rockets. When a rocket hits earth it shrinks.

The game features 3 different enemy types, several upgrades and other pickups.

Controls are fairly standard WASD / Arrow keys / Control stick to move and SPACE / Triggers to shoot.
