Ah I see xD. Yes, I should've explained it better. Well you have to take a diamond and an animal mana and then go to a crafting station. These won't work if you don't have the items in your inventory and hence by default you'll shoot nuts. All throwables do different amounts of damage to enemies.
If you are at crafting station 1: then you should have bronze diamond equipped and if you press keypad0 you get squirrel nuts.
If you are at crafting station 2: then you should have silver diamond and either butterfly, bunny or penguin mana and then if you press keypad 1, 2 or 3 you get coloured leaves, carrots and ice as a throwable.
If you are at crafting station 3: then you should have gold diamond and either elephant, parrot or swan mana and then if you press keypad 4, 5 or 6 you get stone, different coloured leaves and sharigan to throw.
Once equipped the respective slots get removed from your inventory. A bit complicated, I'm sorry about that. I'll try to make a better tutorial scene and maybe improve the levels so that we know what to do and when to craft. Thanks for your comment and thanks for playing!!
