Simple, but solid TD game. There are two types of towers in the game: offensive and support. Offensive towers purpose is to do damage to enemies while support towers increase power of those attack towers. The other twist of the game is that there are multiple paths, but you can’t block or change them, which makes the enemies spread to all directions and you have to strategically plan where are the best spots to concentrate in building your towers.
