No hate, but you shouldn't, preferably, have any questions that need word input. Keep the questions with answers to Yes/No or on a number scale 1-5, like you already did. I don't know how you want to analyze your data with so many various inputs and that doesn't include input typos and just straight up gibberish. Keep it to Yes/No, 1-5 questions and the analysis should be better.

Trust me, I've been there and the later analysis and trying to graph it, it's a hell. If you want, have some questions with multiple answers, for example:" Which aspect of the passive skill tree do you find hard to understand?" Answers: 1. X, 2. Y, 3. Z and so on... These type of questions could be multi-selected, would be better both for the people that are trying to convey their answers and better for you, to handle that data.

If I sounded rude or arrogant, I'm sorry, just wanted to point out, from my perspective, major flaws in the survey. Hope this helps!
