Great to hear you're going to make a series :) Well, if you look around, you'll notice there are twelve "branches", one per month. Each light will lead you to the Monday level of each week. I'll add one light on every Monday. Currently, when the game starts, you're automatically sent to the latest level. Going forward will loop to the the title screen, but if you go backward, you can walk through the past levels in reverse order. Also, you may not have noticed this yet, but each day of the week has its own colors. I hope it helps. Thanks again for your interest!
