Press "1" for Easy Mode, "2" for Normal Mode, or "3" for Hard Mode. Press M to mute / unmute the music.

The yellow number is your money (use it to buy towers, earn it by killing enemies); the purple number number is your life points (how many enemies can pass the end before you lose).

Click any grey block to build a tower on it. Click "Start" or "Next Wave" to start defending against the next group of enemies.

Click a tower to see its range or to upgrade it when on Level 2 or 3. Once you beat Level 1, you unlock the ability to upgrade towers on it as well.

There is a Challenge Level 4 in the editor if you get bored of Level 3.

Watch out for some tricky enemies . . .
