You should add a Battle Pass with items you can't every get again and are very basic. A shop where 1 toy of a Bad-ly made Dragon costs an absurd $70.
Also btw scrolling from a weapon with ammo (such as knife) to a weapon without (such as shotgun) results in infinite ammo. Also leaving the game doesn't bring back up the menu. Seems like it keeps the ESC menu up and never closes or brings up the start menu.
