It's hard to explain, but I was just bored for most of the game. All progression comes in the form of unlocking levels and collecting gold during those levels. That's fine enough for towers, but I'm playing a character! Why doesn't he level up? Why can't he get collect gear? Why aren't there character-specific traps and abilities? Sure, the little soundbites and the victory dances at the end of the level are great (especially the dances, that was an awesome surprise), but that doesn't actually motivate me to keep playing. This game came out after Dungeon Defenders which has all of those things and more, why isn't there any innovation?
Everything else is fine enough, but I wouldn't recommend that someone go out and grab this game. I'm sure the game is a bit more exciting once multiplayer kicks in, but what, really, is the point? They'll be just like you! Just more of the same. I'll have to check out the original Orcs Must Die sometime, but that may be a while.
