I'm really sorry about that! It was a depth-sorting bug in the HTML5 version that made items 'disappear' after restarting.
I’ve just uploaded V2, which completely fixes all those bugs. The inventory and items should now display correctly every time.
I have also added all enemy death animations, and all the weapons now spawn on the chest up to mythic rarities.
I’d love for you to give it another try!
