History

Demo launched June 2025

Originally started as a Game Jam project in 2022. Primary focus is a Steam release in December 2025. From the very beginning, the game has been designed to run smoothly on a variety of devices in landscape or portrait and to support multiple control methods, including keyboard and mouse, touch, and gamepad.

Inspiration

Inspired by Warcraft 3 custom maps, No Heroes Allowed!, Bejeweled, Bloons TD, and various auto battler games. It blends tower defense with auto-battler mechanics while giving you deeper control over placement and strategy.
