Everything in the project is done with the mouse. There is absolutely no need to push any keys. Endless Mode can be played from the start. In Campaign Mode you start with only one level unlocked, but whenever you complete a level you unlock the next. There are 15 levels. Finally, Boss Mode has three different bosses, all of which you can face in Campaign and Endless Mode. At the beginning only one boss is unlocked, but you can unlock the others by beating the boss before it. BOSS GUIDE--Tips for beating Bosses. Boss 1 (Purple): 3 Attacks. When it blasts in a circle, get into a corner. When it shoots lots of pellets to the side and some in the middle, slip in-between them. When it blasts pellets aimed in your direction, just dodge. Boss 2 (Green): 3 Attacks. When it shoots the small pellets that follow you, dodge them until they wear out. When it shoots very quickly, get off to one of the sides. When it shoots lots of medium-speed pellets from each side, dodge slowly. Boss 3 (Red): 4 Attacks. When it shoots quickly down the middle, get out of there. Don't go there in the first place. When it shoots quickly in a circle, do what you can to avoid it. When it shoots slowly in a circle, slip through two of the pellets. When it blasts two half-circles, one from each blaster, go high.
