If you got to a room with a burnable bush, such as R12 (three rooms west of your house), you'll notice two lines of code starting with "IF D12==0 THEN..."

The 12 refers to the current screen. The next variables include variables such as the X,Y coordinates, the palatte, and the sprite number (in this case 572 since its a bush). Do a search for "D12" to find relevant lines of code such as (of course ignore the music sections that happent to have D12 in them):

Line 341: This line tells the game to clear the bush sprites and change the map for the two tiles from 1 to 0 so they can be walked over.

As for night/day, I'm afraid I won't be much of help since I've never incorporated that into any of my games. I'm pretty sure I could figure something out, but I'm sort of on a hiatus from PTC...
