Dark Tower: Nightfall is a 2D defense and progression game where you command a lone tower standing against an endless night. Monsters emerge in waves, each stronger than the last, testing how well you can upgrade your defenses. Your goal is simple but addictive: survive every assault, earn coins, and reinvest them to make your tower unstoppable.

Each wave you defeat rewards you with coins. Tougher enemies give more coins, encouraging you to push further instead of playing safe. Use those coins to upgrade your tower’s damage, attack speed, range. As you grow stronger, so do the monsters — fresh enemy units, higher HP, faster movement — forcing you to constantly improve your build.

The game blends casual wave defense with satisfying upgrade loops: attack → earn → upgrade → attack again. With its stylized dark-fantasy look, glowing projectiles, and progressive difficulty, Dark Tower: Nightfall gives you that “one more wave” feeling. Can your tower hold out when the night sends its strongest creatures — or will the darkness finally break through?
