The foundation is complete, what to build?

Finally got pretty much all of the base features on the Sudoku gameplay finished; Basic sudoku puzzle generation with notation available as well. Some small features like auto-notate when starting a game and cleaning up the visuals and visibility of the notations still need working on, but all in al it's pretty good.

At this point, I'm nearing the end of my time working on this project. Unless this somehow gets all viral and it proves viable, I think I've done as much as I can realistically do with the project given where I am regarding financials and job hunting and whatnot. I may try to get this published on STEAM just to say I've gone through the process, but it's not likely unless I can really polish it up

I've learned a lot and gotten much more familiar with Unreal, but I would like to move on to other projects/ideas I have. I have a pseudo visual novel idea that could be cool, though my drawing skills leave a lot to be desired. I'm also noodling around another idea for a puzzle game, or trying to do something more narrative-focused.
