Could you elaborate a bit on the behavior you would -like- to see, what curves and input buffering would yield, just so I have a clearer idea of what to research?

If you make a platformer you need to make jumping feel good!
You change jump force or/and gravity non-linary to remove this floaty feel
When you press jump just a little before landing and it didnt work it feels frustrating, to fix this you make for jump button a bool and allow it to be activated for some additional frames
