Smiley Tower Defense

You control the placement of towers, each represented by a colored smiley face, along a set path that enemies travel. Your main objective is to stop waves of these enemies from reaching the end of the path. You spend your money earned from defeating enemies to buy new towers or upgrade existing ones. A recognizable mechanic involves combining two towers of the same type to create a stronger version, which adds a layer of strategy to your placement decisions. The pacing starts slow but the waves gradually become more frequent and the enemies tougher, creating a steady climb in difficulty. It feels like a quiet puzzle of resource management and positioning, where a wrong move in the mid-game can force a quick restart.
