[NES] Karnov - Skywalker Code (Super Mario Bros 3) Code Making Help?

Alright, I'm trying to make a Skywalker code for a game called Karnov. The character jumps and elevates between jumps when the jump button is pressed. However, he remains on the same level in the air as to where he jumped to. Watch GIF(s).

If anybody could help me out with this, it'd be greatly appreciated. And yes, you will get credits. My ASM knowledge is very minimal. I know it's within the ASM code that there's a possible Skywalker code. All I need to do is to tell the game to bring him down on each jump. What I've noticed is that there's multiple LDA's (LoaD Accumulator) within the RTS's (Return To Subroutine), so would I need to make a 3 part code from these 3 pieces of accumulator loadings? I don't know ASM, like I said, my knowledge of it is very minimal. 6502 is one of the easiest versions of ASM and to make NES game genie codes, it's very simple, as you can see below. But I'm not a programmer or at least a very amateur n00bish one.

So, like I said, any help will be greatly appreciated and you will get credits if your help got me to make the code. Thanks!
