# Goal

The goal is to catch as many coins as possible during 7 levels. 
Coins appear when you break bricks.
They fly around, bounce and roll, and you need to catch them with your puck to increase your score. 
Your score is displayed in the top right corner of the screen.
You must delete all bricks to progress to the next level. 
If you drop the ball, it's game over, unless you had the "extra life" upgrade.

# Upgrades 

After clearing a level, you'll be able to pick upgrades among a small selection presented to you. 
The upgrade you pick will apply until the end of the run. You will get more upgrade choices, and even the ability to pick
multiple upgrades at the end of the level if you play well : catch all coins, clear the level quickly and never miss.
You also get a free random upgrade at the beginning of each run. You can see which upgrades you have
(and a few more details) by clicking your score at the top right of the screen.

Upgrades apply to the whole run and can synergize. For example, if you combine "sapper" and "piercing", the first brick 
you hit after a puck bounce will immediately be transformed to an explosive brick, and detonated by the same ball, 
effectively giving you an explosive ball.  

Some upgrades help with aiming, like "puck control balls". Some upgrades can be picked multiple times to increase the effect, you'll see for example "+1 ball level 2" which adds a third ball.

When you first play, only a few upgrades are available, you unlock the rest by simply playing and scoring points. There's a similar 
mechanic for levels unlock. At the end of a run, the things you just unlocked will be shown, and you can check the full content in menu / unlocks.

Many upgrades impact your combo. 

# Combo

Your "combo" is the number of coins spawned when a brick breaks. It is displayed on your puck, for example x4 means each
brick will spawn 4 coins. It will reset if you miss. 

Many upgrades impact your combo :

### Single puck hit streak

The combo grows by one when breaking a brick, but resets when a ball hits the puck. 
Once you combo is high, the puck will glow red, to remind you that it will hurt your combo to touch it with any ball. 
The combo does not reset when the ball is lost, provided you have more than one ball.

### +3 base combo

The combo starts at 4, and resets to 4 if another upgrade resets it. 
Picking this again will raise the starting combo by 3 each time. 
There are no downsides to this upgrade.

### Shoot straight

The combo grow each time you break a brick. 
The combo resets whenever the ball touches the left or right of the play area. 
Once your combo is a bit high, the sides will glow red to let you know you shouldn't touch them.

### Sky is the limit

The combo grow each time you break a brick. 
The combo resets whenever the ball touches the top of the play area. 
Once your combo is a bit high, the top will glow red to let you know you shouldn't touch it.

### Picky eater

Each time you break a brick, if the ball and brick color are the same, your combo grows by one. 
Otherwise, the combo resets, and the ball takes the color of the brick. 
Bricks of the wrong colors should glow red once you have a small combo going.


### Compound interest

Each time you break a brick, your combo grows by one. 
Each time a coin falls around your puck and is lost, your combo decreases by one.
Once you have a small combo going, the bottom of the screen will glow red around the puck, to remind you to catch all coins.
If you level this further, then the combo grows and shrinks faster.


### Hot start

Your combo starts at 15 at the beginning of the level. 
Every second, it decreases by one. 
If you level this further, the combo starts 15 points higher and shrinks 1 point / s more.


### Soft reset

Whenever your combo resets, it only looses half of its value. 
However, whenever it should increase, it has 50% chance of staying the same. 
If you pick it a second time, the effect is more pronounced : the combo keeps 66% of its value on reset, but only grows 33% of the time.
If you have many perks that grow the combo every time a brick breaks, then it will still grow every time just slower.
 
# Aiming

What decides how the ball flies away is only the position of the puck hit. If the ball hits the puck dead center, it will
bounce back up vertically, while in you hit more on one side, it will have more angle. 
The puck speed and incoming angle have no impact on the ball direction after bouncing.
You might find that a smaller puck makes it a bit easier to aim near corners, but also makes it much harder to catch coins.
"Wind" and "puck controls ball" can help you aim even after the ball bounced to the wrong direction.
"Slower ball" gives you a bit more time to aim, particularly useful in later levels where the ball goes faster. The ball also
accelerates as you spend time in each level.
