Smiley Arena

Smiley Arena is a single-player game that combines tower defense with direct, action-based combat. Control a smiley character on the battlefield using WASD to move and the mouse to aim, while placing and upgrading turrets across five lanes to stop incoming enemy waves. Choose from six classes, each with a unique ability: Fire for burn damage, Ice for slowing and freezing, Shadow for invisibility and critical hits, Medic for regeneration and healing, Bomb for splash damage, and Speed for a high-speed dash. Defeated enemies provide currency for building turrets and upgrading them through multiple tiers. Level-up choices are made while the game continues without pausing, and bosses appear regularly between standard waves. The full version includes endless waves, all six classes, the complete upgrade tree, and an achievement system. A free browser-based demo includes the first nine waves and the first boss encounter. The game supports English and German.

Smiley Arena is set in a fantasy world of castles, forests, and lava fields overrun by endless waves of grinning attackers.
