working more on spider-behavior and finally adding some sound effects. the sound isn't particularly _good_ yet, but it exists, at least!

pathfinding for large agents: the spider patrols by default and chases you when you're in a place that it can reach (it can't fit through smaller doorways)
eventually this will have some stealthy line-of-sight stuff, but for now the spider just has magic awareness

started adding support for a moving camera - this is harder than usual in this game, because of the lighting system!
getting more and more interested in making the whole game one continuous/seamless map, instead of doing room-transitions...

video of what happens when running the script from the previous post. currently it just prints stuff to the console, but i'll get into proper in-game dialogue rendering soon

making a map editor, partly to make it faster to set up rooms, but also so i can auto-generate these red sectors...
sectors are always rectangles, so any two points inside the same sector are guaranteed to have line-of-sight to each other. this should allow a much faster raycasting strategy!
