Thermamancy — Alpha Prototype

A tactical deckbuilding roguelike where your health is a thermometer.

There are no traditional HP bars. Your survival depends entirely on keeping the mercury within a safe temperature range while balancing powerful fire and ice magic.

🔥 Core Mechanics

🌡️ Your Thermometer Is Your Health

Instead of health points, you must keep the mercury between -100°C and 140°C.

Reach either limit, and the thermometer shatters—ending your run.

🔥❄️ Master the Heat Balance

Fire cards deal devastating damage but rapidly increase your temperature.

Ice cards cool you down and help you stay alive, but usually offer less raw damage.

Every turn is a balance between power and survival.

Current Features

• 5 unique cards (each with an upgraded version)
• 3 elemental enemy types
• Boss battle every 5th wave
• Enemy intent system—see what your opponents plan to do before they act
• Hand-crafted pixel art
• Original gameplay systems built in Unity with C#

Planned Features

• New biomes with environmental temperature effects
• More enemies and unique bosses
• Artifacts with powerful card synergies
• Meta-progression through collectible Mercury Shards
• More cards, mechanics, and strategic build variety

About This Project

This is an early alpha prototype and my first game developed in Unity.

I'm currently experimenting with mechanics and looking for feedback from players.

If you enjoy the concept or have suggestions, I'd love to hear from you. Every comment helps shape the future of Thermamancy.

Thank you for playing!
