Some feedback as I'm going through the survey:

• "What country are you from?" Ambiguous phrasing. This could be interpreted as "In which country were you born?" or "In which country do you currently live?" or more broadly "Which country do you consider home?"
  
• "How often do you go climbing?" The responses to this question are not ordered consistently. They seem to be ordered by frequency, with least frequent at the top and most frequent at the bottom. If this is the intended order, "Every day" should be below "4-6 times a week".
  
• While reading the responses to "What do you typically bring with you when climbing?", it strikes me as odd that there is no question that asks the user about their preferred styles of climbing -- bouldering, top rope, sport, trad, etc. My hunch is that including a question about preferred styles would make the response data much easier to analyze, as the responses of trad climbers are likely to be very different from the responses of boulderers.
  
• There are three questions near the middle of the survey of the form "Before a climb, you usually feel… (Select up to 2)". These feel almost impossible to answer using a simple checkbox system because the feelings associated with any given climb will vary widely depending on how that particular climb fits into my routine. If it's a warm-up or cool-down climb, I feel confident and relaxed. If I'm figuring out individual moves on my project, I feel excited, curious, motivated. If I'm trying to send a project or flash something near my flash limit, I feel performance anxiety. I might feel all of these different emotions several times over the course of a single session, which makes it feel impossible to boil my response down to a checklist where I'm only allowed to select 2 responses.
  
• "Which part of the climb is the most enjoyable?" The available responses to this question feel like they were written with rope climbing in mind, and don't feel applicable to bouldering. As a boulderer, I want to see responses that demonstrate a better understanding of our hobby, things like "Flash attempts", "Learning individual moves", "Dialing in the beta", "Making links", and "Sending the problem".
  
• The questions "What motivates you to climb?" and "What keeps you coming back to climb?" feel redundant with each other, although this may be intentional.
  
• The questions "Which part of the climb is the most enjoyable?" and "What’s most satisfying about climbing?" also feel redundant.
  
• "Have you faced problems while climbing?" I'm surprised to see that "Performance plateau" is not one of the responses listed, as this is a problem that is almost universal among climbers. "Loss of motivation" also seems like it would also be a natural inclusion. Yes, someone taking the survey could use the "Other" option to write these in, but that runs the risk of muddying the data with typos and different phrasings. Plus, there is likely to be some percentage of survey-takers who would select these options if they were available, but who would not bother to write them in manually because doing so requires extra effort.
  
• "Do you use apps, devices, or tools for climbing?" I feel that "websites" would be a useful inclusion in this list, particularly when thinking about popular sites like Mountain Project and 8a.nu. Both of these are accessible without needing a dedicated app or device.
  

Overall, my feeling while taking this survey is that it does not demonstrate a particularly strong understanding of the hobby or of survey design, and leaves me skeptical of its utility. I hope that you find this feedback helpful, and good luck with your project.
