## Powerups & Shop System

**Bullets** - The bullet powerup is the blue powerup which increases the amounts of bullet fired. It does not change the frequency of the bullets, but rather the amount fired simultaneously. You start out with single bullets, then the first upgrade shoots a double bullet 1 out of 10 times, the next will send a double 1 out of every 9, and so on until you have every shot as a double bullet. After this, the process repeats, but with triple bullets. The bullet powerup is made redundant after every shot is a triple bullet, as this is the maximal upgrade. Upgrading starts at 10 coins and doubles until the final upgrade which costs 5120 coins. A maximum upgrade in the shop starts your game with every shot being double bulleted.

**Shield** - The shield powerup is the white powerup which forms a white barrier around the cannon which prevents the cannon from being hit by the cookies. This is particularly powerful in combination with the laser as you can indiscriminantly stand right under a cascade of cookies and still be fine. When the shield is about to finish, it will flash on and off, warning the player. Upgrading the shield in the shop increases the duration of the shield. Upgrading starts at 10 coins and doubles until the final upgrade which costs 5120 coins.
