Well it's been more than 2 months since the Jam started and no one has submitted anything. You should just quit the jam man.
Viewing post in Game Jam extended 7 months due to lack of submissions
There is a reason why the game jam is so empty
Nobody is willing to make new games for DOS; atleast not a considerable amount of people. DOS games; in contrast to other game jams it is purely DOS. Making a DOS game takes time and patiente.
The last game jam ran for 2-3 months and got a few submissions; 15 submissions is op for this type of game jams.
And to spice things up: the game jam is not mainstream, people prefer Unity or "do X" game jam types instead of "code natively for old platforms".
