Alright, got about 4 hours of work done last night before I committed, so committing again today after 4 hours seems appropriate. Here’s the current state of things:

The day/night cycle is in place, and you can initiate it by pressing the spacebar. The time will change every 10 seconds. You can only place buildings at night. We’re getting close to some kind of gameplay, people!

I resolved an issue with bounding boxes on the tiles, but a new issue has cropped up- placing buildings behind existing buildings will make some weird drawing errors. I’m going to go take a shower and hopefully an idea for fixing it will come to me with the sweet, sweet hygiene.
