There's nothing wrong with the laser ring. It punishes players that are slacking with hitting the blue notes consistently. It shows up for like two seconds and then it's gone. Hitting blue notes is a skill you deserve to be tested on by level 5, more than halfway through the game.
Yep. Was much easier to get perfect slides and etc in VR due to the elimination of video lag. I imagine playing it on switch in handheld mode gives a similar benefit.
Though I would also say some of the sharp rapid corner turns are easier to read in VR even compared to a 4k TV due to VR giving a less congested/narrow view of the track.
Yes. The one and only true way to play it.If you're not playing it in VR you're not getting the true Thumper experience. You become one with the beetle.
