Bro needs to add the ability to view your inventory. That's like one of the first things you add in any game that requires you to have things which is like 99.9% of all games.
It's the pouch, you can click on in on the map of the dungeon or during combat. If you want to see the other resources you can check them outside on the inn.
If you mean weapons/relics, it's not visible during the dungeon by design, so you have to commit to the gear you are using when entering.
