Side-scrolling slashers are pretty well-represented on the Switch, though none of them have game mechanics quite like Aeternoblade. Early on the ability you acquire to capture your actions in time and then replay them, effectively either doubling your attacks or allowing for you to trigger switches remotely, adds a nice wrinkle of puzzle-solving to the mix. The action itself can struggle a bit, especially as it switches perspectives at times and the mechanics that work just fine (though a bit spammy) in two dimensions can get a bit wonky when introducing a camera and trying to manage enemies in more open 3D spaces. Still, it has some original elements so that may attract some interest for people in love with the art style or are looking for something a little different.
