Evaluation

Curse of the Sea Rats launched on April 6, 2023 and received a series of post-launch updates. The developer shipped several feature patches through mid-2023, addressing combat improvements, balancing, and quality-of-life changes. In July 2023, Petoons Studio announced a free content update called "The Ghost Ship" survival mode, targeting Fall 2023. That update ultimately shipped on March 13, 2025 — alongside a second new mode called "Jolly Roger" (a casual difficulty option), an enemy bestiary, additional voiceover languages, and extensive bug fixes. This was a substantial content delivery that fulfilled the previously announced commitment. The March 2025 post is the most recent developer communication, and no further content has been announced or promised since. The only DLC listed is the soundtrack, which was released on April 24, 2023. With no unreleased DLC, no outstanding announced content, and no developer statements indicating future updates, the game appears to have reached its content completion with the March 2025 major update.

About this game

Curse of the Sea Rats is a ‘ratoidvania’ platform adventure with lovingly crafted, hand-drawn animations. Embark on the epic journey of four prisoners of the British empire, transformed into rats by the notorious pirate witch, Flora Burn. To regain their human bodies, they will have to fight dangerous bosses, uncover the secrets of the vast Irish coast, and ultimately capture the witch who cursed them.

Beautiful 2D, hand-drawn animation breathes life into the game's cast of characters - inspired by classic animated films and reminiscent of the golden age of 2D platforming. These animations combine seamlessly with detailed 3D environments enhanced by light and shadow effects to create a 2.5D platforming experience of incredible quality.

Chart your progress through a huge, non-linear world as you attempt to track down the pirate witch who cursed you. Shipwrecked on the coast of Ireland in the 18th Century, you'll need more than just your swashbuckling skills to forge your path to freedom.

Discover four playable characters – David Douglas, Buffalo Calf, Bussa, and Akane Yamakawa. Each character brings their unique fighting style to help you overcome the challenges posed by enemies and the environment! Play alone or with up to three friends in local co-op mode.

Each character has strengths and weaknesses. You'll be able to improve their abilities as your adventure progresses - unlocking new special skills, boosting your offence and defence, or learning powerful magics!

A labyrinthine network of hundreds of pathways, rooms and discoveries lie ahead, in a substantial quest with over 12 hours of content. Can you master each character’s playstyle, find all the hidden secrets, and unlock each of the game’s multiple endings?

PLEASE NOTE: Multiple controllers are required for local multiplayer mode
