Same thing I said earlier but nice to see you understand the sameGame jams, in my humble opinion, are for learning, meet new people (devs, artists, etc) and to see what you actually can do with the game jam restrictions (like time, theme). Anything else besides that you simply should not worry about, it is cool be well ranked and everything, but dont take it too serious.
It is also good because we will have a ton of feedback of all kind, people who will love, who will hate or will not give a **** for what you've done, and those feedback are a great opportunity to be better.
Anyway I think that every feedback and critic that is made with respect is a good thing, whether they liked what you done or not, wheter it is a 1000 words review or 1 setence review, it is always a good opportunity to know where you might improve, what are can do better and all that blablabla =p
