Suggested verbs, objects, directions make the game easier than its retro forebears like Zork. None of those helpers were available in most text adventures back in the day. For experienced players who know the "secrets" of adventuring (take anything you can, look at everything, use undo and save often) the first 50 rooms feels like following a tour guide. The game is fair if you know these "secrets". There are reportedly 300 rooms so perhaps there are greater challenges ahead.
In a large map, back-and-forth to take the found key to the locked door etc. is more tedious. I think the graphical map helps the sense of movement. Some games allow teleport between distant locations.
Some dead ends can't be reverted by undo so save often.
