Hello!
I'll definitely see to adding more checkpoints. Though I might also have to consider the 'nonlinear' part. Some choice options can change depending on other choices you've made. I'll see how to integrate all this. For now, as I've mentioned in my game description, I strongly recommend players to save the game from time to time.
Thank you for sharing your thoughts! It's always helpful to know what players think!
Good luck for the jam!
