Mirror Siege is a fantasy strategy auto-battler made for Game Jam 4.

Build your army, roll new unit choices, deploy squads, counter the enemy composition, destroy six defensive towers in order, and finally break the enemy Castle.

The current jam build features:

• 12 Unit Types with different roles and counters
• Player vs AI
• Roll-based unit shop
• Squad deployment
• Increasing Gold income over time
• Tower damage that becomes more dangerous during long sieges
• Large-scale battles with many units on screen

This is an early Web prototype. The current version focuses on one complete battlefield and the core gameplay loop.

The project is being developed with an AI-assisted workflow using ChatGPT for game design, balancing, documentation and asset direction, and Codex for implementation, debugging and technical iteration.

Future ideas include larger maps, deeper terrain strategy, more units and factions, online PvP, ranked matches and tournaments.

Controls

• Mouse: interact with the shop and UI
• Choose unit quantity
• Drag purchased squads into the valid deployment area
• Fullscreen is recommended

Feedback about balance, AI, deployment, Gold pacing and Tower difficulty is very welcome.
