## What is Ironclad Abyss?

Evolve your fighter against endless mech-swarm in cosmic fissures.

Game introduction: 
In the randomly generated cosmic fissures, pilot an evolvable super fighter to face the endless horde of mechanical insects - every jump is a brand-new challenge of life and death.

"In a shattered universe, your fighter plane is the last beacon of civilization."
This is a shooting game that combines 3D sci-fi air combat, roguelike mechanics, and a dynamic evolution system. Players will pilot a bio-mechanical fusion fighter to battle against self-replicating mechanical insect swarms in a procedurally generated star domain. After each jump, the battlefield rules will be restructured - from weapon combinations to physical laws, even the AI logic of enemies will change due to your growth.

Game Features
Each round randomly generates weapon modules, enemy ship types, and cosmic environments, ensuring endless replay value.
Dynamic difficulty curve: Adjust the strength of enemy ships and the behavior patterns of bosses in real-time based on player performance to avoid repetition.
