Thanks for the feedback!
- The graphical requirements are high, but it really is necessary for this type of game. I've optimized as much as I can already.
- You can restart instantly by pressing 'R' or right-clicking (it is listed in the controls).
- I do actually use a combination of torque and drag already, you have tighter controls when on the ground and looser control in the air. The problem is that fractals are really bumpy so you often find yourself in the air more than you'd like.
