you dont need any twitching really the w key +space makes you jump roll holding right mouse button should enable u to steer a bit the rest is just timing if tht doesnt help then i suggest get as far as you can make a platform then save till u complete it also on some platforms if you aim to hit the wall this will stop you from over shooting ,If its the ones that fall when you land just keep the w key pressed while tapping space bar it should go as one fluid motion
hope this helps
Thanks for the suggestion, but my objection is having to learn to make my hands learn the "hold w key while tapping space bar and stearing" task. If I wanted to do that(or was good at it) I'd play some kind of Action Game on a Console. I like RPG's on a PC because generally you can Think your way through every situation.
Buy a gamepad / speedpad...Nostromo or Logitech.
Never worry about button configuration again...I too hate having to stretch my hand across the keyboard and hope I hit the right key at the right moment.
I own a Logitech G 13 and never been happier...I only use my keyboard for typing and setting up game profiles.
