I agree with your approach!
I much prefer a low score with honest feedback that I can use to learn and do better on my next project rather than generic "I love your game" feedback that, while it makes me happy in the short term, doesn't give me any information about what did I do wrong and what can I improve.
I think that the most important thing about game jams is learning opportunity that this kind of "events" offers you.
I would love an honest feedback from you:
