Pandora's Tower is one of those few games that make great use of the wii motes motion controls, while in the heat of battle using the wii's motion controls to aim the hero Aeron's chain to tie up monsters allowing you chances to attack them freely, attach them to objects to limit there range or even just to rip there flesh clean off is expertly implemented. As is navigating the enviroment while swinging or pulling yourself or objects, and definitly is the strongest point of this game.
The story is fairly simple but implemented well and I won't spoil it for you; but the basics are that the woman you love has been cursed and you have to travel to the fortress of the 13 towers in order to obtain Masters flesh, Masters being the boss creatures each tower has one and your girlfriend needs to eat the flesh of each to break the curse. Each tower is themed around different mechanics of using Aerons chain weapon and are nicly implemented.
The background of the story is mostly presented through documents you collect through out the towers and range from researchers notes on the towers and their functions, day to day life, the Masters and their weaknesses and notes from the towers past residents. Presenting game world in a manner similiar to games such as the Souls series from From Soft.
Overall, if you enjoy richly crafted worlds such as Dark Souls or Nier, and are a fan of Action Adventure RPGS, you'll probably enjoy this game.
The game was actually really freaky, where in some scenes where the girl has to eat the flesh in order to keep the curse away, gross! Other than that, the combat and level design is OK...nothing too amazing. Let's put it this way: God of War combat system is much more efficient (although different).. it's much more polished because the developers took the time to make it like that. Pandora's Tower was overall just that: unpolished. The towers got veeery repetitive in the sense that many rooms looked very similar in layout. It had pretty interesting moments here and there, but overall, the pace just lacked in wow factor. So...overall I'd recommend that you "look" at the game before you "rent" it. See for yourself how the game plays on YouTube: search "Pandora's Tower gameplay" and you'll see for yourself if it's for you.
