Surfacing

One day, Lumi the mermaid visits a new underwater town where seemingly nobody believes in mermaids. Determined to prove true mermaidhood, Lumi sets out to collect mermaid artifacts from the surrounding area. Lumi is joined by Toivo, who might also be a mermaid.

Surfacing is a Game Boy-style RPG in terms of color depth and screen size. Just pretend the resolution never changes due to text boxes, menus, or combat.
