Thanks for playing our game :D
We decided when developing the game not to do a tutorial in the classic way, but rather to force the player to understand how the world he's in works. The first island allows the player to understand the main mechanics of the game.
As for crafting, we wanted the game to take players out of their comfort zone, so the player will lose all his resources if he dies, but he won't lose the potions in his hotbar, forcing him to use his resources at the risk of losing them.
