I love HoD. It's spooky, unpredictable and downright bizarre, in a good way. And the soundtrack is, in fact, brilliant. The actual compositions, that is. My only gripe with HoD are some of the sprites. The way Juste moves is just...wrong... And yeah, the game isn't that challenging, but neither is AoS, CotM, DoS, PoR or SotN. I even found OoE to be a bit on the easy side, but hey, that's just me...
Other than that, HoD is slightly better than both Aria and CotM in my humble opinion (which are good games too).
