You're absolutely right. For this jam I've been posting non stop for the past three days to get my game noticed and that's because of a prior experience I had with my last game. I worked on my first ever big game project called Avarice last year and finished it earlier this year and released it. I posted about it the day it was released and for the next few days but not many people played it. Eventually the game got to 80 downloads but to this day no one has commented to say if they liked it or not or even offer feedback. I have to be honest, it made me feel down that a project I had put so much work into got beaten by the much smaller game I had made for this jam in just two days with about four times as much views. What I've learnt from that however, is that every part of the game making process is equally important, not just the actual development of the game. That's why I'm over the moon that so many people are playing my game One Shot In The Chamber (the game I made for the jam) and are enjoying it so much. My only regret was that I did not see Avarice all the way through to the marketing stage as I have with One Shot In The Chamber.
