I got a LOT done today! I added a new cutscene that makes for a better lead-in to the dream sequence cutscene, edited the house maps, designed the tree farm map, learned how to have characters randomly wander about, wrote the big Tree Debate that kind of spurred this whole story idea on, AND learned how to both edit existing scripts and add new scripts in order to create a less-cluttered pause menu! And considering how stressful a weekend I had + how crazy work was today, this amount of work was great.
Tomorrow, I finish up Act One (and if I play my cards right, I'll definitely hit my 30-minute length goal!) and also start adding music. My normal source for royalty-free music has a bunch of Christmas songs, so I'll probably be using some of those. Depends on how the various tunes the engine comes with sound. Then some double-checking for errors and Act One is done!
This game is actually turning out really nice so far. I feel pretty good about putting a price tag on it.
