The twisting stairs being the only way to get up is bad for motion sickness. I wish the teleport thing let you go up and down floors as well in rouge's bar.
The sensitivity on the teleport thing is also off, I often end up spinning wildly to one side while trying to teleport. This doesn't happen to me in other games where ticking the controller back does an action.
I wish that if you teleported to the edge of wall, you wouldn't be looking right into the wall. It also messes with motion sickness. Being pushed a little back so it's not in your face directly would be great.
It's a really great game though
