Petoons Studio, the Barcelona-based developer of Curse of the Rats, aims to make family-friendly products to be enjoyed together, including toys, animation, and video games. Its latest Metroidvainia offering certainly fits that bill, with its nostalgic animation style, simple progression, and relatively easy combat. The simplicity and ease work in its favor, making Curse of the Sea Rats accessible to a wide range of players, yet not so trivial as to make it unchallenging. Unfortunately, several bugs and some odd choices make it somewhat cumbersome, especially toward the end.
