Inventory\Pause system + mobile controls

A small inventory sketch, like a pause, like a quest tracker. I want to make it so that during the game, there is nothing on the screen, except for the sight when the player holds a weapon. Especially for this, I came up with a gesture to open the inventory for mobile phones, a swipe from two fingers from top to bottom (left and right), like a curtain opens, only with two fingers, what do you think?
