Curse of the Sea Rats (Switch) Review - Nintendo World Report

Curse of the Sea Rats has received several significant updates on the Nintendo Switch to address launch issues and improve gameplay. As of early 2026, the game is widely considered much more polished than its initial release. Latest Updates and Major Changes

Animation Cancelling: Attacks can now be canceled with jump and parry actions for faster, more dynamic gameplay. Sailing Through the Storm: A Guide to Curse

Control Tweaks: Movement and combat responsiveness were improved, and hurt animations were shortened.

General Fixes: The map UI was updated, pitfall deaths were disabled, and the end game was smoothed out.

March 2025 Patch: A newer update reported by players improved late-game stability and fixed specific exploits, such as the "fireball soul" farming method. Switch File Types (ROM/NSP) In the context of the Nintendo Switch:

NSP (Nintendo Submission Package): This is the standard file format used for digital game installations, updates, and DLC.

Installation: For users of custom firmware, updates are typically installed via tools that manage .nsp files, while legitimate users update directly through the Nintendo HOME Menu. Exp Farming Post-Patch The Technical Side: NSP vs

Since some exploits were patched, players recommend the Temple area on the far right of the map for farming experience. Specifically, a ghost enemy near a save point in this area can be farmed for roughly 300 EXP per kill by repeatedly exiting and re-entering the screen.

The Technical Side: NSP vs. XCI vs. ROM

When searching for curse of the sea rats rom nsp, it helps to understand the file differences:

  • NSP (Nintendo Submission Package): Digital-only format. Used for eShop games, updates, and DLC. This is the most common file type for patch updates.
  • XCI (Cartridge Image): A 1:1 copy of a physical game card. Rarely used for updates.
  • ROM: A general term for a read-only game file, but in the Switch scene, “ROM” often incorrectly refers to an XCI or NSP.

For updates specifically, you want an NSP file. The base game might be an XCI or NSP, but patches almost always come as NSPs to overlay the existing game data.

Gameplay Tweaks

  • Adjusted hitbox detection for Bussa’s anchor attack.
  • Increased the drop rate of health vials from basic rat enemies.
  • Added a new minimap icon for hidden breakable walls.

What is Curse of the Sea Rats?

Released in early 2023, Curse of the Sea Rats is a love letter to classic 2D action-platformers. Blending the nonlinear exploration of Metroid with the punishing combat of Dark Souls (and a heavy dose of Rayman’s hand-drawn aesthetic), the game puts you in the role of one of four prisoners.

After the dreaded pirate witch, Flora Burn, transforms your crew into rodents, you must fight across a beautifully illustrated 18th-century Ireland to break the curse. With four playable characters (each with unique abilities like ranged magic, heavy melee, or agility), the game encourages multiple playthroughs.

Gameplay Impressions: Is it Worth the Hype?

If you enjoy games like Hollow Knight or Ori and the Blind Forest, this one is right up your alley. However, it has its own distinct flavor.

The Pros:

  • Visuals: The animation is top-tier. The character movements are fluid, and the backgrounds are lush.
  • Combat:
