At least give the players a goal or purpose to play ... instead, we are left wandering effortlessly through 6 different maps for no reason then to explore. But even exploring can get boring, if we aren't given a purpose.
As for the achievements, just run the game for 5+ minutes and you'll get 100% easy. So there's no challenge getting those either.
Excluding the Mars and the Apocalypse map, the rest you can just visit IRL. You'll get a better experience doing that. Even for a free game, Relax Walk VR was a waste of time for me.
