Yeees! The save system was a stroke of genius. Ha ha. I love it for testing too. I know that's such a dev thing to say but it's so useful. Rofl.
And yes, Kav shows up in Chapter 3! Buuuut. I did want people to get to meet him so he does have a bonus scene that unlocks at the same time Noel's unlocks. So you can get a brief glimpse of the space hobo. But he won't appear in the story until the next Episode.
