Yep - play literally any resource management boardgame.
Also, re; incrementals - try to think of the top-level goal of the limitation.
We want you to focus on making something sensibly-scoped, reasonably polished, and genuinely enjoyable for the judges (i.e. your other jammers) to play in the time they have available to play and rate games.
Incrementals are generally designed to drag minimal content out over a long period of time. You totally can make one within this brief (for example having visual resource tokens which are worth X amount of the previous token type, on a curved value scale) but it's also worth noting that the genre doesn't lend itself to something which comes across well in a 5 minute session.
Better to use this jam to practice how to do UX and gamefeel stuff in a project which fits the brief and then take that learning forward into your longer/slower games, rather than trying to force a longer/slower game format into the jam when it's unlikely to do well under the voting criteria [which have been devised specially to try to get you to focus on the moment to moment feedback and legibility of theme and mechanics, rather than larger more complex systems!].
