There is a small, minor bug, I've experienced it and some other screenshots show it too. When you unpause the game, the button still shows paused. Other than that, amazing game! Love the inventory system, I always find that fascinating!
Thanks for letting me know, I really appreciate the feedback as well :) The inventory system was definitely the trickiest part, and it's still far from perfect. (I made it using scriptable objects in Unity.) If I were to add features or redo it, I'd allow for items to swap slots and drop on the ground.
