Kill Those Monsters

Waves start automatically. Left-click of a tile to place a tower. Towers are randomly chosen and the cost for each one starts at $50 and goes up each time a new tower is purchased.

Towers can be merged by selecting two of them and clicking merge (it costs money).

Only towers of the same type and level can be merged. Clicking on the path clears the selected towers.

Don't let the monster reach the other end!
