It was available during the jam timeframe, and also was an official Unity asset provided to users, so your submission is still fine.
I wasn't talking about my submission but somebody else's. The only external resource I used (so far, might change if I get to adding some sounds to it) is the open-source font that I added to the game's page now as well.
So, if I want to build that other game, would there be any chance to still get that asset?
