1. THE STORY
Welcome to the Underground Hazard Lab, Chief Scientist! 
A severe system malfunction has mixed up highly volatile, 
toxic chemicals inside the containment tubes. If they 
are not properly sorted, a chain reaction will destroy 
the entire facility. 

You must take control of the lab's Robotic Arm, sort the 
dangerous liquids, and stabilize the lab before it's too late!

2. THE OBJECTIVE
Your goal is simple but challenging: sort the colored 
liquids so that each test tube contains exactly ONE color. 
A tube is considered "safe" when it holds 4 blocks of the 
same chemical or when it is completely empty. You win the 
level when all active tubes are stabilized.

3. CONTROLS
The game can be played using the Keyboard:

* LEFT / RIGHT ARROWS: Move the Robotic Arm.
* SPACEBAR: Pick up / Drop the liquid.
* R KEY: Restart the current level (if you get stuck).
* S KEY: Toggle Sound (ON/OFF).
* P KEY: Enter Password mode.

4. HOW TO PLAY (RULES OF CHEMISTRY)
* You can only pick up the top layer of liquid from a tube.
* You can pick up multiple blocks of the SAME color at once.
* You can only drop a liquid into an empty tube OR on top 
  of another liquid of the EXACT SAME color.
* You cannot drop a liquid if the receiving tube doesn't 
  have enough free space.

5. THE CHALLENGE
The game features 32 mind-bending levels. 
As you progress, you will face:
* Taller stacks and fewer empty tubes.
* Hidden "Mystery Blocks" (?) - You won't know their color 
  until you pick them up!
* LEVEL 31: Limited Moves. Think carefully!
* LEVEL 32: Time Attack. A 180-second meltdown countdown!

6. PASSWORD SYSTEM
Don't want to lose your progress? Every time you clear 
a block of 5 levels, the game will reward you with a 
4-letter password. 

During gameplay, press 'P', type the password,
and hit ENTER to jump straight to that level.

7. SYSTEM REQUIREMENTS
* Standard MSX 1 computer (or emulator).
* 16KB RAM minimum.

Good luck, Scientist. The lab depends on you!
