1. Smooth Sliding: Tap and drag left or right on the canvas, or use the A/D keys (or left/right arrow keys) to control the lateral movement of the Nano-Assembly Core at the bottom.

2. Precise Base Assembly: Keep an eye on the **target gene sequence** displayed at the top (e.g., `A` ➜ `T` ➜ `C`). The falling letters are `A` (blue), `T` (green), `C` (yellow), and `G` (purple).

3. Avoid Red Viruses (☠): Collecting the wrong nucleotide letter will **reset your assembly progress**, while colliding with a **red viral spike (☠)** will cost you one heart of health.

4. Huge Point Rewards: Successfully assembling a complete gene codon sequence triggers a massive point burst, which is converted into gold coins and deposited into your account!
