Cosmic Summon is a gacha merge tower defense game I built as a solo indie developer.
The core loop: summon heroes, place them on the battlefield, merge duplicates to evolve them through 7 rarity tiers. Face 28 enemy types across 50 constellation-themed waves — each wave named after a real star pattern.
12 heroes, each with a distinct ability. Boss encounters every 5 waves.
