25% of the way through :)
After some more hours put to good use (mostly), I have implemented a nice chunk of the gameplay mechanics. First, the levels make a bit more sense now, and is populated with notes and randomly walking NPCs.

The NPCs are at first completely grey, but picking up certain notes lets you see some of their colors. I have also gotten the field of vision detection to work.
Now, I need to step back and think of how I want to go forward. There are several things I could implement right now, but I need to prioritize.
But so far so good, I’m on track for having all the gameplay put in today
Hope you are all doing okay!
