I'm glad you enjoyed! To answer your questions:
- The mac savegame file should be located in ~/Library/Application Support/Heather Flowers/EXTREME MEATPUNKS FOREVER/save.mpx -- I'm not 100% sure on this since I don't own a mac, but it's the likeliest place to find it.
- Season 2 will be a separate purchase, and your decisions in S1 have a number of effects on the game's story. Not just the big decisions, too -- lots of little decisions have a way of coming back!
- The reason for the departure in character design is twofold. First, S2 has a different character artist (Ryan Rose Aceae, who also worked on GENDERWRECKED), and second, everyone's been trekking across the wilderness for over a week now and the wear is starting to show. Like, they're just sleeping on the ground. None of them are feeling or looking great at this point, and the artstyle has been updated to reflect that.
