Based on my analytics, most people do not browse the rest of my offerings. They look at the single project that they found in search.
I assume this because they'll find one of my graphics packs using the term "gothic" and only view that one package. I have three "gothic-themed" graphics UI packages. If they had clicked on my profile, they would most likely have viewed all three.
I had thought of creating a different page for my graphics and games - but instead I've just changed the names. My graphics start with "Graphic pack" and I sorted them to be right at the bottom of my page below my games. You could do something similar with your jam entries.
Having several completed game on your profile might give someone more confidence to buy one of your games, as they can see you have some experience and the game will most likely work.
