Do my choices in earlier chapters carry over to Chapter 5?
Yes. Your save file transfers your inventory, recruits, shadow crystals, and key decisions (like whether you spared or defeated bosses) into the subsequent chapters. If you start Chapter 5 fresh, the game will assume a standard default state.
Is Chapter 5 free?
Yes, if you purchased the game. Toby Fox stated that buying the game once (priced at $24.99 starting Chapter 3+4) covers all subsequent chapters up to Chapter 5 as free updates.
