Ahaha that's so true about the feedback, I read the comments on my game and I'm thinking "Wow I'm like winning here" but then I see similar comments on games that are mediocre to terrible. Some people just want the karma, I think.
That's actually a really good starting point, though, right? Being able to produce a functioning game with beginning, end, gameplay, sound, music, animation, all that. With that as a goal you definitely succeeded and you're in a good place to extend that. My first game jam project had miserable balance (almost nobody got past level 2 of 10), no sound whatsoever, and colored squares for the graphics. I just ran out of time.
