In the 2D tower defense game Limited Defense, you use the mouse to hire different units to protect your tower.
Move the cursor to the right icons and press the left mouse button to interact with the game's UI. When enemies get close, your active units will attack on their own. The goal is to make it through all of the waves of enemies. On the right, there will be gold and wave counters. At the top, there will be more tower health. You lose if the tower's health drops to zero.
Each arena in Limited Defense has its own waves of enemies you have to survive. Once you decide on one, you will be shown a map of all the possible positions and the way to the tower. At the far end, there is a portal that the enemies will come out of and follow the path. The prices of all the units you have available will be shown at the bottom. As time goes on, more units will become available. You can put a unit on any open square after you buy it. The unit's attack range is shown by the gray circle around it. If you click on the unit, you can sell it or improve it. Enemy health bars will show up above their heads, and if any of them get to the castle, they'll do damage. Every enemy you kill gives you gold. Keep defending until all of the waves are over.
Because the name Limited Defense suggests, you only have a few defense options, so you need to make good use of them. While ranged units have better coverage, they also have less power. Melee units, on the other hand, are the strongest but also have the fewest options. You should look for places in the path where you can put the best mix of units to do the most damage all at once.
