Tiger Vasopressin

"## Gameplay

### Game Objective
The goal of the game is to eliminate all viruses on the screen. Once you successfully eliminate all viruses, you advance to the next level.

### Controls
There is a virtual controller at the bottom of the game interface that you can use to control the falling pills:
- **Directional Keys (Left/Right): Move the falling pills.
- **Directional Keys (Down): Accelerate the pills' fall (soft drop).
- A Key: Make the pills drop instantly to the bottom (hard drop).
- B Key: Rotate the pills clockwise.

### Elimination Rules
- Align the falling pills with viruses or other pills of the same color.
- When four or more blocks of the same color (viruses or half pills) are connected horizontally or vertically, they are eliminated.
- Pill capsules are made up of two halves of two colors, allowing you to eliminate viruses of different colors simultaneously.

### Game Over
If the pills pile up to the top of the screen, preventing new pills from spawning, the game ends.
