Controls
Use WASD to move the black square in the center of your screen (your square).

Left click to place traps under your square. Right-click traps to remove them from play and bring them back to your inventory.
Gameplay
After a minute of playing, enemies will begin to come after you. If you get hit by an enemy, it will take away some of your health (the pink bar in the top left).
Place traps to destroy enemies so they split into point squares.
Point squares fill up your level bar (the green bar in the middle bottom). When it gets filled, you level up, gaining access to more traps in your inventory as well as upgrades to your square or new types of traps.
Towers are scattered around the map and offer various boosts to your square or your traps. Or (like the blue and pink towers) they may spawn squares.
Colors
For the most part objects in the game are color coordinated.
Traps will be pale green, pale blue, light yellow, pink, or orange.
Enemies will be red (threatening), dark purple (dangerous), light purple (vicious), and black (formidable).
Point-related items will be a light green.
Health-related items will be pink.
Slowness-related items will be a light yellow.
That's it your all ready to play!
