Black Cat is hyper minimalistic addictive (or relaxing) game with one never-ending level and zero (clear) graphical design.

Rules

Your goal is simple: fall as deep as possible and score as many points as you can.

You get points when you: 
- hit blue, red and grey lines
- bounce back (black and red lines)

The score for each hit depends on the size of the line and on your speed. The grey lies give you the most points.

You gain health when you:
- hit a blue line
- bounce back (black and red lines)

You loose health when you:
- hit red lines
- are falling

When is the game over?
- When you loose all your health.
- When you fall out of the level.

Advice:
- Always watch your health.
- If your cat (black rectangle) is blinking red, you are about to die.
- Hitting a line with great speed gives you more points.

Under 'Infotek' you can:

- See your scores.
- Turn music on or off.
- Turn sound effect on and off.
- Choose between 'Tilt' and 'Tap' modes.
- Choose if the score or the background should flesh whenever you hit a line that gives or takes health. 

Have a good time!
