Thanks for trying it out, Tomo!
-The First Person/Third Person switching has been addressed and I have an update planned for today, but thank you for confirming how annoying it can be.
-I've gotten so comfortable with how the inputs are, I just didn't even think about changing them before I uploaded, so I will revisit those.
-The quests don't actually work at the moment, so I'll just add some text to indicate that instead of displaying broken buttons.
-Didn't even know climbing in first person was possible! This will be fixed today, thank you!
-When you fall off the Great Wall, there are vines near the pirate ship that the player can climb up. More vines will be added to various points so the player won't have to backtrack so far. I'll mess with the swimming so the player isn't walking on water anymore as well.
-I will also be adding some subtle hints and a few signs to direct the player around the world.
This is some great feedback, thanks again!
