The players running all over the place and looting everything is part of the uniqueness of a tabletop RPG in a videogame setting.
An example I'd give is the fact that while the dwarf was talking to the slimes, the elf went behind them and looted the crypt, causing the slimes to attack immediately.
It's not a big deal, and can definitely lead to funny situations, but it can get a bit old or not fit a slightly more serious story. Just something GMs and players will have to agree on for a given story.
Another thing that kind of stood out to me was the judicious use of resurrect scrolls. That's part of the arcadey aspect of the game of course, but it did feel out of place in a GM'd session, like there wasn't a huge amount of consequence to anything except a full party wipe. Not sure what an alternative would be other than simply removing scrolls from the game. Given how easy it can be to just randomly die, not sure if that would play well. Maybe if the players got a big boost to their health, they'd really have to screw up or face a tough enemy to die.
