Fifth exhibit.
Ah, another old script of mine. I'm not sure if I'll set myself up for DS TASing again, but here's one game I was analyzing and never told anyone about here.
Since I don't have things set up, I can't say with certainty what it was about. I do remember being able to switch between individual stats of individual planes, and I also remember tweaking the script to display my missile data and the closest distance to a particular target it managed to reach. Fun stuff to mini-TAS a part and hit something with a not-homing missile from very far away. No, I do not have it recorded.
Freedom Wings is another one of those games that aren't the greatest out there. Or even all that wonderful, really. You're not missing much by never picking up this game.
