I LOVE quick looks. It is my favorite part of this site and most of them give a great idea of what game is and how it plays. However, this one fails to show what this game has to offer. I think this is because a game as complex as this demands a better first experience than what the developer provided. The game starts out looking like a very simple tower defense game with four very unbalanced classes.
The squire epitomizes the word overpowered in the first section of the game. His towers are second to none and can still murder enemies at a quick pace. And the other three classes are mainly either good at combat alone (huntress), have sub-par towers (apprentice), or a supportive role (monk). The game quickly shifts away from that set up though especially in the higher difficulties. The monk has auras and which are necessary to beating the harder challenges especially if under geared. The huntresses traps do amazing damage in the mid game while taking down the harder monsters with ease with her weapon. The apprentice can build / repair towers amazingly fast, set off an oh shit mana bomb that clears out everything around him, and has the highest damaging towers.
More than just all 4 classes becoming useful this game has depth in the sheer amount of modes available. Solo play, co-op, pvp (kinda awful but its here), Pure Strategy Mode (only can build towers, no combat), Mix Mode (changes up the monster types attacking at random VERY HARD), Survival Mode, and 12 challenge missions. Each mode is up to the person to decide if they are fun, but they add a layer a depth and longevity unrivaled by any other tower defense game.
