I've not had time to implement the climbing ability, unfortunately, but if you do find any eggs you struggle to click or need to get from weird angles, I suggest switching to first-person mode (by scrolling upwards until the camera snaps into place)
This can make it slightly easier to access eggs and dialogues, as well as giving a move immersive (though less stylised) experience of the game.
It is undoubtedly more terrifying in first person.
