Space NanoEscape

Backstory:
You were captured by series of wild nano-machine built spaceships!

You've fallen all the way to the second innermost machine!

To get out you need to destroy all the nanomachines on the level, otherwise the spaceship gets rebuilt and you'll fall to the lower level

Controls:
Shoot: Space; Left click; Bottom button on a controller
Move: WSAD; Arrow keys; Mouse movement; D-Pad; Left stick
Pause: Escape; P; Back button on controller

How to play:
You start at level 2. To see on which level you are, simply pause the game

Your objective is to destroy all the nanobots: 

Each colored enemy shoots different bullets. Yellow ones go straight down. Red ones move from side to side and green ones go in circle.

If you any of them leaves the screen, you will see Arrow down: 

If you're successful, at the end of the level Arrow up shows up:

Arrow up means, that you moved to next level! If you missed any enemy during level, you move to previous level at end of level.

At start of every level (except level 0) you fight a boss. 

Careful! Each boss is different and has different attack pattern!

Beat level 10 to Escape the evil nanobots!

During bossfight, BOSSes HP is shown on top. Red bar is his remaining health.

During the stage, the top bar shows your progress through it.

The bottom bar shows your HP, as you get hit it depletes and changes from green, to yellow, to red.

The red squares are your remaining lives. You start the game with 3 lives, but you can get more by defeating bosses. Each boss gives you a little bit of HP, which can increase your lives.
