A nothing game. Takes the approach of Order of the Phoenix, in that it's mostly about running from one place to another, always doing fetch-quests specifically this time around, with only the occasional minigames serving as gameplay, but doesn't have that many minigames, and the ones it does aren't great. They are more difficult, however. On average at least, nothing really beats that one Gobstone minigame from Order. You do get rewarded with an occasional rail shooter segment or two (Half-Blood Prince really likes its shooter comparisons that's for sure), though it isn't much. Regardless, the gameplay is really mindless, and you'd really benefit from using the speedup option on an emulator.

Instead of going for prerendered backgrounds, the game has its own artstyle and environments, though it obviously takes a lot of the assets from the other games. It generally looks unimpressive, sometimes kinda funny, like a handheld JRPG from that era almost.

What is a bit frustrating is that the game does have spells for overworld use, and chooses to use them only for furthering the minigames. There is an Order-like game somewhere in there, but the minigame focus goes too far and upsets an already poor balance those games had.

(As of writing this, the most popular emulator hangs up on a loading screen early on. If you really want to play this, do try another emulator, and even if it has graphical artifacts you should still be able to get past the train sequence and yoink a savestate that you can use. The rest of the game works fine.)
