Quick yet smooth code made in ~3 hours, original code ~10 minutes. i to toggle info p to toggle jetpack b to change bounce, j to change jump strength, m to change max speed, a to change air resistance, f for friction and g to change gravity. DON'T SET GRAVITY PAST 250 OR IT'LL GLITCH OUT! Also refrain from setting air resistance above 0 or below -1 because you'll accelerate constantly :/ if friction is set to 0, the ground won't apply friction. Same with Air Resistance
I recommend setting friction to 0, air resistance to 0, bounce to 1 (all y velocity is sustained at 1), and gravity from 0.5-0.1. ADHD cured. Something interesting I noticed is that if bounce is set between -1 and -5 you will sink. Don't set the bounce to 0 because it'll stop you from being able to do anything.
