I'm pretty sure that most here would consider that to be a reasonable amount of asset reuse/repurposing. Like I originally intended to use a menu system that I had made a while back for the title and pause menus in my entry (I ended up not using it because it was going to take too long to adapt it to the way I decided to draw GUI elements to better handle variable screen resolutions, but I digress). It's the small handful of games that made it into the jam that were originally completed months (even years) ago that only had a few adjustments made to better suit the theme of the jam during the jam period that seem to be getting people a little salty about the loose rules.
