I don't understand people like that. Someone didn't like your game, they wrote about it, what's wrong with that? They just gave you feedback and wished you luck in your future projects. I didn't see anything negative in your review, some people just don't know how to take criticism properly.
Don't forget that half (if not more) of the participants are teenagers and children. And we know how children react to criticism.
Btw, in overview of this jam was recommended not to form a team of more than four people, as it is difficult to coordinate so many people in one week. However, unfortunately, these recommendations were ignored by this team.
All I can wish for you is to be lenient.
