Whipped up a test room to figure out the daytime and sunlight mechanics while in the “overworld” (basically, outside in the city). The length of the shadow is pretty much hard-coded instead of calculated in real-time while outside because the effective lightsource is the sun, so your position doesn’t really affect the length of your shadow.
3 times of day are shown, which are roughly morning, noon, and evening/sunset. Different puzzles in town can be solved at different times of day because you’ll need your shadow to be able to reach certain areas.
There will also be nighttime levels which are like a time attack mode, where you have to get to a puzzle before the moon gets to a certain point in the sky so your shadow is at the right place at the right time to solve a puzzle.
You can also now slide out of a crouch.
