Much like a few other tower defense games on the site, this game has a limited number of slots to place the turrets in. In later games, you will need to switch out the turrets, which is costly. You also have two power ups (tar and dynamite pigs), which take a while to recharge. Use these power ups with care. They are often your first and last lines of defense.

Players experience a spike in difficulty almost right away. After the tutorial levels, it becomes more difficult to maintain the 5-star rating. The enemies get stronger and come at you fast. You may need to replay each level as you go along. Especially annoying enemies like the aliens can muddle your gameplay. Make sure your turrets get to them fast.
