Mastering Soma's movement and combat controls is paramount. The game utilizes the Nintendo DS's buttons for most actions, with the touchscreen primarily for the Magic Seal system and map navigation.

- D-Pad: Move Soma left/right, crouch (down), and climb stairs.
- A Button: Jump. Press again in mid-air for a double jump (after acquiring the appropriate soul).
- B Button: Attack with your equipped weapon. Hold for continuous attacks with some weapons.
- X Button: Use your equipped Bullet Soul.
- Y Button: Use your equipped Guardian Soul.
- L Button: Backdash. Essential for dodging attacks quickly.
- R Button: Activate your equipped Enchant Soul (passive ability).
- Start Button: Open the menu screen (Inventory, Equipment, Souls, Map, System).
- Select Button: Toggle the map display on the top screen.
Practice these movements frequently, especially the backdash and jump attacks, as they will be your primary tools for navigating dangerous areas and engaging enemies effectively. Experiment with different weapon types to understand their attack patterns and range.
