I've noticed people are submitting videogames to the jam. Some seem genuinely proud of their work and possibly misunderstood the jam. Others didn't even answer the submission question. I know some people just submit their game to every jam they can as a bad form of marketing (I've seen games with literally hundreds of jams in their submission lists).
The rules don't explicitly say tabletop games only, but I assume that was intended to be implied by the name of the jam?
A quick glance found these, just checking the ones that had a videogame-y thumbnail or no summary text: OOO, Lone Army, snake, Move with Moons, Blorb enters the eye of the universe, Inday, Finding Silly, Ari, CreepyBoratory, Croft Freezer, Space Battle, Box-ing
