Here are weapons that should I used to make the game easier. 1-57, missiles(both kinds) and laser lock until I got duck death/big lazer. Replace laser lock with duck death and 4x missiles with big lazer. level 58, use big lazer every time you use slow time(2 weapons) when slow time runs out, hold down mouse 1 on lightning. Use the same strat on 59 if you want, or go back to missiles. 60 use Duck Death, Laser Lock and Energy Missiles. You don't have to pay attention to where you aim so concentrate on dodging. Slowly tap around the outside of the box, when he shoots star shapes, just keep a far distance and he should beable to hit you that easily. Big pockets to go through. Re-post this small guide by Sirk if it helped!
TIP FOR LEVEL 60 IF YOU ARE TOO DUMB TO DODGE
Buy Time Slow, Energy Missiles and Duck Death - Use Time Slow when it gets dangerous and dont overheat the Energy Missiles :) worked for me
This game has a few bugs, e.g. if you hit the ball with the side of your bar it goes to the ground, bounces strangely but you dont lose lives... please fix :)
