This prologue is really really good. It plays well, the portal mechanics are fun, the platforming it challenging and satisfying and the metroidvania was not overly backtracky making it a really pleasant experience. The dialogue needs some work TBF, but the dev recently announced on twitter that they hired a writer to up the quality on that as well so my hopes are really high. This has potential to be ne next Ori or Hallow Knight, will be keeping close tabs on this one
