I mean it was very hard to see the obstacles sometimes. For example, there was one section where you had to float up a cliff and over some spikes with antigravity. But the way gravity works means I died twice on the spikes because I didn't know they were there the first time and that there were more than I expected the second time. Then, because the camera shows very little (especially below you if you are currently falling) I landed in the very last spike (dying a 3rd time).

Basically, my critique boils down to, the player being effectively shortsighted.
