Okay, I normally don't support Nintendo in suing people for copyrights, but these devs have no excuse if that happened; Like, wtf you can't make it more obviouson whom you are copying the art style from.
I looked up the... "dev" Wisnu Sudirman (they've never released anything) here's a list of their previously announced games, all on the PlayStation store:
Survival Builder (release date 2025)
Rooted: Survival (release date 2026)
Super Capybara Adventure (release date 2026)
Orbital Station Simulator (release date 5/2026)
Supermarket Tycoon Multiplayer (release date 6/2026)
The Legend of Meowda: Brath of the Wild Cat (release date 7/2026, removed from listing, presumably for copyright issues)
Bikini Beach Kombat (release date 9/2026)
Anime Village Online (release date 2027)
Valhalla Online (release date 2/2027)
Counter Force (release date 3/2027)
They all look like mockbusters, a few of them have more images with a google search, but the images all look AI generated or at least filtered.
