VOID ESSENCE

VOID ESSENCE is an incremental tower defense game that blends deck-building strategy with real-time tactical placement.

Build your deck from a pool of 37 cards — units, structures, and spells — each with unique stats and abilities. Place them on the field during combat, manage your essence economy, and unlock permanent upgrades between runs. After each level, earn shards to purchase new cards from the shop or receive random card rewards. Between waves, choose from three passive upgrades that persist for the duration of the level, stacking power as you push deeper.

Features:

- 37 unlockable cards across 3 rarities (Common, Rare, Epic) — melee units, ranged turrets, crystal structures with chain/splash/slow/freeze, and offensive/defensive spells

- 10 passive upgrades chosen between waves (Vitality Boost, Sharpened Blades, Frost Aura, etc.)

- 5 campaign levels with escalating difficulty, each with 10 waves and a boss encounter

- 6 enemy types including Scouts, Brutes, Ranged, Exploders, Elites, and Bosses

- Persistent meta-progression: cards, shards, and completed levels carry between runs

- Deck builder: customize your starting hand (4–8 unique cards) from your collection

- Per-level card shop where you spend shards earned in combat
