Some keyboards, especially laptops have limitations on how many keys can be pressed at once. This game is absolutely horrible in those cases since generally you want to be holding something like w, a (or d), shift, q (and/or e) (4-5 keys) and a lot of people rebind reel in/out to keyboard buttons as well. I recommend looking into if you can turn on n-key rollover on whatever you’re using or (as a last resort) rebind hooks to mouse. Also you almost always want to hold shift (gas) when playing. There is an option under rebinds for Auto-Gas which will hold it for you whenever you are in the air and then can tap to disable (slow down) which might also help your ghosting input issue.
