Okay, so Mermaid Melody is one of those weirdly charming GBA rhythm games based on an anime about singing mermaids—yeah, you read that right. You tap buttons to the beat of these bubblegum J-pop tracks while the characters belt out high-pitched notes in frilly costumes. It’s not exactly Elite Beat Agents, but there’s something hypnotic about nailing a combo as the screen explodes in sparkles and dolphins.

The Japanese-only release means you’ll be guessing menus at first, but the gameplay’s simple enough—just match the scrolling notes. Some songs are deceptively fast, though, and failing means watching your mermaid dramatically faint mid-performance. Weirdly addictive if you’re into niche rhythm games or the anime’s brand of sugary chaos.

Also, yes, the title is as ridiculous as it sounds.
