I would definitely patch your bugs and also respond to any early criticisms. I think that is totally fair.
I increased the number of enemies that spawn, fixed a controller bug, tweaked the scoring structure, and added a bigger pickup to mine based on an early review. It didn't even occur to me that I wouldn't be able to fix/tweak my game after I published it. I intend to continue fixing/tweaking and adding stuff after the jam is over.
