Also you will get money when you beat levels. You can spend your money in 2 different shops and you can go to the crafting area to craft some tools with the items you just bought. But, it is important to spend your money correctly because if you die 5 times in a level, you will lose some money! Can you advance and kill the immortal king? Is it even possible to kill an immortal?
