Are there any constraints on the submittion game's genre?

I'm just wondering because of the games published by Degica games, which seem to be more narratively driven and JRPG-ish.

Looking through the winners of last year, they seem to fit that genre as well...

Do the submittions have to be in any way similar, or are we allowed to take a more actiony approach? For instance, could I submit like a rougelite bullet-hell shooter, or an abstract hardcore platformer, or other kind of game that's more focused on mechanics and gameplay rather than story?
