In summary of this thread:
The system is flawed, people more so
Somewhat sarcastic jokes aside everyone will inevitably have their own subjective bias towards things; what is original/etc. to me is not necessarily the same to anyone else. Maybe I won't agree with them, but it's hard to say someone's opinion is wrong in most cases. And yes, some people did make games based on one of Mark's examples, but is that so bad? It's not original in the basic idea, if you really want to look at it that way, but how it's executed can be.
Besides, end of the day most (if not all) of us put a lot of heart and soul into making our games, so things are going to sting (to put it midly).
And I mean, what would you rather take from this: the results of an arbitrary rating poll, or the fun making your game and seeing the cool things other people made?
Honestly speaking:
Is this partly to convince my tired childish mind? Yes.
Am I satisfied with my result? No, but I'd say most of that stems from knowing what I couldn't add, couldn't change, couldn't fix, and the pointless worry of "would that have improved things for me?"
And in the end, what do a few stars really say about your own game?
I'd say not a lot; I got much more from feedback in the comments, and I can actually do something constructive with that. Jam's over, doesn't mean I'm finished with the game, not by a long shot~

Side note: if it helps, look at the rating system like Amazon reviews. I'll leave it to y'all how to interpret that~
