Regarding the launch date, you could mention that the game has been launched on Nov 15, 2016 on Playstation VR. We also made a game for Samsung Gear VR released on Jan 16, 2017. Of course, the mobile experience wasn't the same than the PC/Console version. The experience isn't a free roam like the PC/Console version so this explain the ratings; the expectation of having the full game on mobile wasn't delivered. The reason is pretty simple, the performance of the PC/Console is of course far better than a mobile phone. Since it's a different game, you could have just a mention in the text but not showing Gear VR as a true platform of Time Machine VR.
For the reviews, you can find a list I've attached. It's not an exaustive one but you could pick a few (or all of them) for the wifi as well.
