Great game, swapping personality traits of the characters, or more specifically the boxes they put themselves in, is a really interesting way to interact with the story. I assume you're a fan of life is strange, since there's a spoof poster of it in the game. I've never played life is strange, but your game kinda reminds me of it in the sense that it's a story-driven magical realism game. I'll do a couple more playthroughs to see what new endings I can discover.
Edit: just go the "stillwater" ending. Cool that the ending where you make no swaps is one that has a special name. Maybe this time I'll try doing every swap.
