AeternoBlade is one of those games that’s frustrating, not because anything in it is broken, but because brief glimpses of excellence show what could’ve been. It's a decent game, but mediocrity rears its ugly head in nearly every aspect. You could do much worse with Metroidvania games than this, but there’s very little here that you haven’t seen done before, probably better. If you are chomping at the bit for every Metroidvania you can find for Switch, then perhaps AeternoBlade is worth the punt. If that’s not you, we’d suggest a better release in the genre - such as like Axiom Verge or Shantae: Half-Genie Hero - and to sit this one out.
