Thank you so much! I'm happy that you enjoyed the game <3
The game has an auto-save at the beginning of each chapter, so it's not something you can manually do as the player.
Also, RC was made in Unity using the Fungus plugin which sadly doesn't have a log/an easy way to implement one. I've played some Ren'Py games since, and ooh boy does it have some good in-built features.
If I need to update the game again, I'll make sure to look into that line-skip issue.
Again, thank you for playing and for taking the time to write such a lovely comment!
