Idle Merge Tower Defense

RUINWALL

The wall is already broken.
The question is how long you can keep it standing.

This is not a pristine fortress. It is the last broken remnant of a great keep. Cracked flagstone. Mossy walls. Dying torches.

You are not building something new. You are holding the line with what survives. Place turrets on the grid. Drag identical turrets together to forge higher-tier siege weapons. Watch coins pile up while you sleep. When the wall can take no more, prestige, and rise again stronger.

Three Loops. One Addiction.

Merge

Drag two identical turrets together on a 5x5 flagstone grid. They fuse into a higher-tier siege weapon. Simple to learn. Impossible to stop.

Idle

Turrets generate coins passively. Close the tab, come back later. Your wall kept fighting. Your treasury kept growing. Offline earnings calculated to the second.

Defend

Waves of corrupted enemies march toward your keep. Each wave harder. Every 10th wave, a boss. Your merged turrets are all that stands between the wall and silence.

Not horror. Not grimdark. Not cartoon.
Think Kingdom Rush meets Darkest Dungeon.
Crumbling stone that still holds. Torches that still burn.
