About this game

The developer's description, from the game's Steam store page.

Hello everyone! Welcome to the first game from Don't Say Game Studios. We built a retro-inspired top-down arcade shooter — and we're excited to share it with you.

Defend Earth from alien invasion across 4 themed levels set around world landmarks. Upgrade your ship between waves, command AI companion wingmen, and face massive bosses with unique attack patterns. Choose from 4 difficulty modes, collect power-ups, and chase high scores with a dynamic scoring system.

We hope you enjoy it as much as we enjoyed making it. Thanks for playing!
