Transhumance ver 0-1-2

Hello Hello.

Here is a small update on the game, with a few fixes while I work on the plot

• Reworked the movements of the Herd... Now they are much, MUCH more dumb, which mean it's easier to control their movement, especially make them fall down a ledge.
• Fixed the carrying and throwing of objects. Now it's a lot more stable, and the character is physically holding something.
• Fixed the behavior of the Mole. Now it won't try to tunnel toward the player anytime you jump
• Added an highlight for items you can interact with the Mole or the Dragonfly, when you have the adequate ability selected.
• Added just a little bit more tutorial.
• Made the dragonfly smaller, so it doesn't block the view as much.
