With the exception of a forest and a cave, the game takes place entirely on Hogwarts and its terrains.

Debug mode
Debug mode can be accessed by typing set engine.playerpawn harrydebugmodeon while in game. It shows the Unreal Engine in the top part of the screen, which has notably green characters. It may not work the first time, but if the player keeps trying or uses the wand it will certainly activate. The key F7 may be pressed to turn it off.

Once in the debug mode, the player can access the level list in the main menu and play any level any time (although the save books may not have effect when the debug is on).

By pressing a certain key on the top left region of the keyboard (which can vary depending on the keyboard type, although generally  '  or ~), the player will open the game command engine. Then the player must type bcheatsenabled true and press enter. Once this is done, the following cheats can be inserted (not all of them will work all the time and they may not work at all sometimes):


 * ghost - opens ghost mode
 * fly - opens flying mode
 * walk - deactivates ghost and flying modes
 * givebeans - adds an amount of beans
 * givehousepoints - adds an amount of Gryffindor house points
 * giveseeds - adds an amount of seeds
 * giveallcards - adds all Wizard cards
 * harrysuperjump - makes Harry makes a very high jump when typed (may also work outside the engine)
 * harrykoresh - makes Harry invincible
 * killharry - makes Harry faint
 * killall - stun all other present creatures
 * setspeed - accelarate the game speed
 * quit - quits the game

Trivia

 * Peeves does not appear in the film, but is battled on a regular basis in this game.
 * The Forbidden Forest part is not included in this version
 * In the book and movie, Neville breaks his wrist (after falling off a broomstick from a great height) during the flying lesson. In this version, Neville does not break his wrist (Because he didn't fly and fall off his broomstick from a great height at all). But the Flying lesson happens early and chasing Neville's Remembrall from Malfoy happens later, In Which Neville gets upset when he arrives and suggests that Malfoy has stolen his Remembrall.
 * In the book and this version of the game, Malfoy says he might leave Neville's Remembrall on a tree for him to find, but in the film, he suggests to leave it on the roof.
 * In the film and book, Harry's broomstick is jinxed in the first Quidditch match. In this version, both Quidditch matches have no Jinxed brooms or accidents.
 * In the book, Quirrell summons ropes to tie Harry by snapping his fingers. In the film, Quirrell snaps his fingers to make fire surround the area. In this game version, Quirrell moves his hands to conjure fire around the area.
 * Norbert seems to appear early in the game, unlike in the book and movie where he appears nearly at the end of the story.
 * Originally Reparo, Verdimillious, Avifors were to appear in this version of the game. In addition, there are several spells that don't make an appearance anywhere else in the franchise, including Flintifors, Ectomatic, and an unnamed transfiguration spell. Also Incendio and Wingardium Leviosa were to have more uses.
 * The Dursleys were to appear in this version of the game because they have their model files still in the game.
 * Harry fights Draco with Christmas crackers. Though, in the book and movie, Harry doesn't fight Draco at all until Year 2, despite challenging Harry to a duel (that didn't happen) in the first book.
 * Harry gets trapped in the dungeons before Potions class, what doesn't happen in the book or the film.
 * In the opening level, when Dumbledore converses with Harry Potter, he briefly alludes to the Room of Requirement, citing he once found a room filled with Chocolate frog, and returned to the same room only to find fire crabs inside instead.
 * However, as the layout of the game's castle does not correlate perfectly with the book, this may be a coincidence.
 * In addition, the Room of Requirement was not mentioned in the books until Harry Potter and the Goblet of Fire.
 * Also, the room always contains what one is looking for, and it seems unlikely that Dumbledore would have been looking for Fire Crabs.
