I love the game so far but is there any way to get a good end with the guide?
Aha, well, maybe? His route has two endings; one where you choose to listen to him right before reaching the shore and one where you decide it's better to not do that. Then there is a totally different route that has a choice option which gives a special guide-centric epilogue . Whether or not any of that is considered 'good' definitely depends on the player. I'm sorry he's such a difficult one.
