Welcome to That's NUTS! -- a casual tower defense game where you help Hank the Squirrel defend his park from invaders. Fire four different kinds of nuts with your slingshot, each with its own special ability. Grab power-ups that fall into the playing area for a quick boost when things get chaotic. Race against the clock and survive for as long as you can!

At the beginning of the game a steady stream of critters will try to make their way across the screen. Critters start off on foot, but over time they'll learn to use parachutes and drop into the middle of the map instead of starting on the edge. The game ends if too many of them successfully make it to the other side.

As your score gets higher, your chances of encountering a rare Hawk, Grasshopper or Mangolin go up. All three of them have ways to avoid your regular defenses and pose an extra challenge!

Each time you fire your slingshot a random nut is chosen -- you can tell which type is coming up next in the game interface. The most common type is the Acorn which bounces up to 3 times on the ground before disappearing. The Coconut breaks and creates a slowing puddle as soon as it hits the ground. The Pistachio explodes on impact with the ground, hitting all nearby critters and power-ups. Lastly, the Walnut creates a vertical barrier that blocks critters. All nuts can bounce any number of times after hitting a critter, but they lose speed from each bounce.

Hitting a power-up using any kind of nut will collect it and earn you a small, temporary advantage. The Clock power-up freezes time for 5 seconds and stops all critters in their tracks. The Heart grants you an additional life, and the Skull eliminates all critters currently on the map.

You can pick a theme to customize the appearance of the world and the outfits worn by critters. Keep track of your personal scores, stats and achievement in the game itself, and fight for a spot on the global leader board.

Best of luck!
