This tower defense game abandons excessive defenses, focusing on building winning strategies with minimal units. Score tiles spread across the board over time, while decay erodes them. You purchase units with coins and stack them on the same tile to build your “deck.” Effects weak individually chain together when stacked, creating combos like triggering enemy attacks. Units decay over time; when they reach zero, they convert surrounding score tiles into decay and destroy them. Place too many and you clutter the board; place none and you can't defend.・Victory Condition: Convert the entire board into score・Defeat Condition: No score remains・Economy: Manage with initial coins, base income, and unit revenue・Construction: Chain effects through stacking and cooldown management・Enemy Behavior: Attacks units or score, spreading decayRemove the unnecessary, leaving only meaningful moves. The less you defend, the sharper your choices become.
