If you're a first time game jammer and made it through to submitting a game, well done.
It doesn't matter if it's complete, or buggy, if it's your first jam, it's possibly the first game you've posted, and submitting it for others to play is a massive achievement in itself. You put the time in, made a game, and let other people see it.
If you got feedback, this can reassure you of what you did right, and help you figure out what you might need to improve on.
As much as we all chase after the top spots and good ratings, even if you don't do well in the ratings, you've done well getting to this point.
We're all learning and chasing after the same dream, so welcome to the party and good luck.
