I love the passive aggressive tone of this post.
I feel like, at least for me personally, there's some reason why people don't give feedback/enough feedback:
1.) Some of their opinions are subjective. For example, "I don't like this jump" or "This looks/feels weird". Map makers (usually) tend to just say "well I disagree with you, I like it" and just disregard stuff like that. At least in my experience.
2.) The map/jumps itself is really hard/long, which is really off-putting for a lot of people because they don't want to spend massive amounts of time playtesting some RNG sync/long wallpogo (like what Boshy said).
3.) Lastly, it's the truth that the vast majority of players on Tempus don't care about testing maps, they're just there for points/grinding.
Don't get off-put by negative comments here and there, ignore the flames and learn from the good criticism you get from players. Can't wait to check out your next map!
