I'm privileged to say I had the opportunity to play Echo VR at Oculus Connect 6 last year. My feelings about the demo are mixed. On the one hand, the game seemed incredibly watered down, even neutered. However, this is just the visual side of things. If you can get past the graphical downgrade, you'll be amazed at how well the gameplay mechanics have survived the translation. The tracking can be somewhat shaky at times, but it mostly holds up. I admit I never tried to deliberately brake it. I was too busy marveling at how well my hand would make contact with hard surfaces. I was amazed that this mechanic seemed to work just fine on the Oculus Quest.
