Frustrating
I have completed Super Hexagon, and it didnt feel as frustrating as One More Line. Restarting is slow and feels like punishment, controls are useless unless you see the tutorial screen (Ive missed it and struggled with controls for a while). The slight delay after the "rope" reaches the axle and the flyer making its own calculations to decide which axle to attach to makes my failures feel like something that happens randomly, not something under my control. And there are some bugs (?), like invisible axles.
