I never played Yoshi’s Island, but Woolly World is a little more forgiving than that. You can focus on just the things you haven’t achieved so far (such as full life or all flowers). One thing I’m not sure about is whether if you’re missing a flower, for example, you have to get all five in a future run or just the one you’re missing.
If you meet all goals in a single run, I’ve noticed that it shows an extra little drawing on the summary at the end, but I haven’t noticed that becoming part of your permanent record.
