A shame these older Strider games have such crappy programming (I applaud anyone who can master the wall jump in this Micronics tier NES game sloppiness) because they have some interesting ambitions narratively. You could say it's because the game is also very ambitious gameplay wise due to its metroidvania nature, but they didn't need to do a Super Pitfall-esque huge level which is stored in memory but fails to be smooth when Capcom already made the NES Captain Commando which also was very ambitious for its time.

It's also ridiculous this NES game drops the fact you are trying to rescue your sister when even the crappy Sega Genesis Strider II remembered that at the end
