Is it acceptable to work on framework and editor elements (i.e. the components/structural elements for building a visual novel, and editor-tools to aid such building), given that those elements are not specific to any visual novel?

To explain, I have a "visual novel framework" that I developed for a third-party non-visual-novel engine (that engine being Panda3D), which I used to make a VN for a previous jam into which I entered. At the moment I'm working on a visual editor for that framework, and have it in mind to rework some elements of the framework itself. Is such work okay, or does it disqualify me from entering this jam?
