To use this feature, activate it by pressing a certain key combination. After that, you can navigate with your inventory open. Next, there is an interesting trick related to invulnerability. To implement it, open the menu and teleport to the gate of dreams. During the teleport animation, close the inventory, and then open it again. When the animation ends, you can close the inventory — your character will become invulnerable. Note that the invulnerability effect will remain even when moving between different rooms. To activate this trick again, you will need to restart the game.
