Idle Tower Defense

Idle Tower Defense is a 2D idle clicker where a lone tower in the center of the field holds off endless zombie waves. Only you can support it. The tower shoots automatically in all directions, while each new wave brings tougher, more aggressive enemies. Your job is to invest resources into upgrades and stay alive as long as possible. After each defeat, you start from the beginning, but the experience you gain lets you survive longer in the next run.

How to play?

For every zombie you kill, you earn food and spend it right in the middle of the fight to upgrade your tower. Increase health, regeneration, attack power, attack speed, and range. Food upgrades are temporary and reset after each defeat. Between waves, go to the shop and spend coins on the same stats; these upgrades are permanent and carry over between attempts, and your long-term progress depends on them. When you have saved enough money, unlock dynamite to deal with especially hard moments when zombies come from every side, and the tower is barely hanging on. Keep offense and defense in balance: weak armor will not survive the later waves, and low damage will not let you clear the field in time. Try to survive as many waves as possible and destroy as many zombies as you can.
