The gravity fields were a bit finnicky but when they did work the game felt really nice to play. I think using the pen to dash actually felt really good and dragging instead of just clicking in a direction is a lot better than what it would've been otherwise.
The only issue I personally had was that looking up and down was difficult to use, and it would stay on when I jumped, which made it hard to see in the other direction. For example, if I was trying to go up and fell, I couldn't see the gravitational field underneath me to catch myself.
