You don't have anything to worry about because I truly understand how college eats up your life. I'm about to start my 3rd year in college and let me say-- I truly didn't expect how hectic and fast paced it was. So I understand the hiatus you have since your studies are also as important.
But it's great to see an update on what's currently happening with the demo! I'm excited to try out your new visual novel (hopefully I'm not too busy as well...)
Take care of yourself in college! Remember to take breaks and not to get consumed by how everything works, good luck and I'm excited to hear what comes next for the game and your endeavors~!
