Tower defense, or as I like to call it, "Why Did I Think Building a Wall Would Work?" is a fancy way of saying you’re playing a strategy game where your main job is to stop bad guys from crashing your party! You get to channel your inner architect and strategically plop down towers and traps like a kid with a Lego set gone wild, all while trying to figure out how to keep the enemy from snagging your snacks. It's basically a game of “Not Today, Invaders!” where your biggest worry is whether you’ve placed the cannon in the right spot or if it'll just end up shooting at the clouds.
