BASIC CONTROLS: Hold down your mouse to shoot towards your cursor. Use the arrow keys or WASD to move. Try shooting the balls to get money. You get $1 for damaging a ball, and $5 for defeating it. If a ball touches you, you start taking damage. UPGRADE INFO: Click on an upgrade/boost to purchase it! Click on the Upgrades background to switch between buying Upgrades and Boosts. OTHER INFO: You will regenerate over time. Each wave is predetermined, except after wave 15. ENEMIES: There are 4 types of balls: Basketball: A normal enemy; 5hp, medium speed. Tennis Ball: Faster than a basketball, but weaker. 8 Ball: The first ball with a unique gimmick! Homes in on the player, dealing massive damage, with 10hp, but really slow. Big Basketball: A basketball but now with extra strength. With 25hp, this monster can pose quite a threat! Luckily this ball is quite slow, and also doesn't home in on you, unlike the 8 Ball. TIPS: Try staying in the center, as balls spawn on the edge. Try focusing on one ball at a time, or else too many balls may hit you. If there are too many balls, try staying in the corner, then come out after there are not many balls. The best first upgrade for beginners is Faster Reload.
