I saw the trailer for your game and it looks pretty good, I didnt say the time it takes to create a game sets the quality, but you should definitely work more on it and then release it, especially if its a game that requires payment to play. Besides that, if you want to win the game jam at least set it to free during the game jam period, then you can make it payed. This just seems like you are trying to promote something, like kind of an ad. You would also get feedback from the community to see what you can fix or make better before you sell your game. Look at this reply as a personal suggestion and stop fighting against all others.
