This is probably a dumb question and has already been answered but...

Is it OK to fix bugs during the voting period?

I already uploaded my game Shifty Drifty dungeon, and its finished. However some people in the comments are informing me of crashes and performance drops. I, who personally, tested my game had not experienced any of these issues. Maybe my computers a monster, I don't know. They were pretty helpful in pinpointing where the issues were though.

I don't want to polish my game, I don't want to change the levels, I don't care about graphical glitches, I don't want to add new gameplay mechanics, I don't want to fix audio glitches, I don't want to change the difficulty balance, and etc. 

I just want to keep my game the way it is, playable from beginning to end, without someone's computer quitting on it.

If not, that's fine. I'll upload a patched version after the voting's over.
