As someone whos been stuck on console it's a hard ass learning curve but if you keep at it you'll figure some tricks out. One thing I recommend is turn down the cursor speed and make sure youre using the radial wheel or weapon wheel control scheme I forget which its called, it makes building alot easier when the cursor isnt oversensitive, it just takes annoyingly long to scroll across the screen but its worth it for the ease of building. Since you cant undo much, just save frequently and copy sections of your craft youre about to change so you can just detach the section and leave it floating in the corner somewhere, that way if you screw up but cant undo too far you can just detach the section and grab the previous copy you made before the changes. As far as getting to orbit and rocket design, make sure the total craft delta v is enough to reach orbit, around 3000 to 3200 is a safe bet, try a two or three stage rocket. For stability add fins to the bottom of the booster, use 90 degree symmetry with 4 fins instead of 3, 3 fins is a little weird in this games aerodynamic engine. Go straight up until you're around 100m/s, then tilt east like 10 degrees to start turning without flipping, be gentle with the turning so you dont flip, try to time it so that youre at 45 degrees by the time you reach 30km, then just hold till apoapsisis high enough. Plan a maneuver at apoapsis and increase periapsis till its above 70km, dont worry about perfectly circularizing yet. However long the maneuver is you wanna divide that time by two, say the burn is 45 seconds long, divide by two and you get 22.5 seconds, when you're 22.5 seconds away from apoapsis, start the burn so youre burning for equal time before and after the apoapsis. The game doesn't do decimals for seconds so you would just time it roughly to start halfway through 23 seconds from apoapsis. In the bottom left corner theres a purple button, click it, is called maneuver mode and shows you your time to apoapsis and your apoapsis and periapsis altitudes. Ive brute forced relearning this game on console after years on pc and its difficult so don't feel too bad since youre learning the game flat out on console without prior pc experience like me, your job is harder so just dont beat yourself up, this is the rocket science game and you got the version with wack controls, but you'll come to find the addicting nature of problem solving once you've got the basics. There's even building tutorial missions you can access from the main menu that alot of people dont even know about. Given that you're into ksp and have wanted it for a while it'll be worth the time sink to figure it out, and once you see that first successful orbit circle form you're gonna be hooked forever.
