I like that game and though I figured out the never ending treadmill, It's just one more dungeon.

What first starts as a typical strategical Tower Defense game is more a 2d, top down Diablo Clone, without the action element.
You grind levels, become more powerful, maximize magic find, loot runes, stack and combine them, become more powerful to absurd levels and then blow maps up.
You can always push the limit, by advancing waves of enemies or stacking runes against you, both resulting in more loot and xp, which in turn makes you more absurdly power.

I like almost everything about the game, except the inventory management.
