Select the map you want to play on. Next, you can change the towers you will play with and click on the towers to see their stats. Then you can upgrade perks with coins. Finally, you can start the game by pressing the "Play" button. You start with $100, and will get more after finishing waves and killing enemies. With this money you can buy towers. To open the tower shop, press the arrow near the top-right. Hover over each of the towers to see their name and price. To actually buy one, click on its icon and click where you want it to go, it can't be too close to the path or other towers. If you don't want to buy it, but have clicked it, you can click on the garbage can that appears in the bottom-right. Once you have bought a tower you can open its menu by clicking it. In this menu you can upgrade it, delete it (without getting money back) and see how much damage it has done, though not 100% accurate. To start a wave press the play button in the top-left, you can only do this once all enemies are dead. To see what wave it is look to the right of the play button, to see how much money you have look below the play button. To lose, you must lose all of your hearts. This happens when an enemy gets to the end. You will lose the same amount of hearts as how much health the enemy has left when it reaches the end. To see how many hearts you have look in the top-middle. If you want to watch someone play this game: https://www.youtube.com/watch?v=INoyvbz1fiI
