Now with a dialog system! One step at a time and this thing is slowly turning into a game. I suppose I want to build towards some kind of tech demo, wherein all the needed features to build a full game are implemented and exercised. The flight mechanics need a lot of polishing, the NPC logic needs to become far more complex, I want other type of NPC beyond pigeons, I want to reintroduce inanimate objects, there needs to be a lot more art (and things like animated background assets), etc. Once all that's done I can focus on plugging the pieces I have into something that's actually entertaining.
