Precisely that. Repeating all the steps to get up to a certain point, trying something different, failing and having to do them all again until you beat that section. Then you get to the next bit, fail and start over.

It reminds me a little of the final(?) map on Super Mario Odyssey: https://www.youtube.com/watch?v=3nyFu1kud-s. It's probably 5x longer than any other map and any time you "die" you have to start from the very beginning. It took me dozens of attempts to beat it, but for some reason I stuck with it. I didn't fancy doing this with Another World sadly :(
