Not every game is going to resonate with every player, that's especially true when switching genres (Urban Fantasy to SciFi). Most players who've been playing it seem to enjoy it so far.
If I see actionable feedback I agree with I respond to it. Unfortunately, "The game is shallow and has no world-building" is not actionable feedback (and I don't agree with the description). That's okay; you're entitled to your own opinion, and if this game isn't for you, hopefully some other game will be instead.
