Haunt the House: Terrortown is in essence a game about playing the man behind the haunted house curtain. As a lonely ghost (or so I would assume, given the story centers around reclaiming the souls of others so as to collect a band of ghost friends...or something like that) it's your job to float around and posses objects to scare the living daylights out of party goers until they either abandon ship (sometimes literally) or out of stubbornness end up dead at your ghostly hands.
The problem I have with HtH is that there really isn't enough - it - here. It's mechanics are incredibly shallow and inconsistent, largely boiling down to spamming random scares until the person you are scaring finally gets the idea and fleas the scene, which doesn't really give you much of anything to work with. It never feels like you have any real control over anything, as people will run any which way they want often irregardless of how scared they are or where the source of their terror is. It makes actually getting anyone out of the house (or wherever you might happen to be) rather tedious and uninteresting, like you're shooing flies with a newspaper, occasionally lucking out and hitting one.
I guess it's somewhat a blessing then that the game is completable in under 30 minutes, as any longer and I'd likely have dropped it out of boredom, but that then falls back into the issue of there not being much of anything here. It feels like a free game fancied up into something that might resemble a fuller experience, which is pretty much exactly what Terrortown is: a slightly larger version of the original Haunt the House flash game, which more than likely lasts as long as you would want to spend with the game, and is far easier to recommend being that it's still freely available.
