Yeah sure but if your game has bad design choices I have no reason not to say "yo, the passability in this map is BULLCRAP WTF FIX IT" or "having 100 scripts means nothing if they're all tacked on with no thought put on it", "yo these map transfers suck", "yo the text is not readable" or "using custom/purchased resources does not hide the fact that this is badly made". A regular player can tell you what they like and not, but dev criticism (while obviously has bias) can help pinpoint super easy stuff to fix if only you know the framework.
Also I'll keep shouting "WHAT DID YOU EXPECT? It's a freaking JUDGED CONTEST WITH PRIZE MONEY". Good on you if you're happy showing off a crappy first project but when placed next to a polished product on a scale you can't expect the same response. (And besides, it's not in anyone's job description or streaming cred to prop you up particularly, they're usually there to entertain an audience if at all.) Besides, obviously streamers don't think to much about what they're saying. It's a STREAM OF CONSCIOUSNESS sort of media.
Srsly, don't give up and all that, but don't try to push the idea that everyone needs to be babied about feedback IN A BLOODY CONTEST.
Tl;dr do your thing and don't give up, but understand people don't owe you anything and a contest environment has a competitive and harsher edge. If you don't feel you can handle that, don't start from there. There are other much friendlier places where an early game can be seen more kindly.
