Misunderstood
It's probably been said a thousand times already about this game - Multiplayer is a MUST.
If you like games like Lost Planet 2 and Monster Hunter, then you'll find a lot to like with this game. It's essentially a boss hunt, but done in the 2D Castlevania universe. And although I seem to be in the minority here – it's awesome fun.
There is plenty of loot to be had, enemies to be killed, and the levels are essentially giant mazes to get lost in. The zoom out/in feature is perfect, and allows you to plot your course with ease - while never stopping the action. The addition of a countdown timer adds to the tension, and the item collecting gives you options galore.
The negatives? Confusing menu system. That's really my only minus point on the game.
Overall, it's a fun game that I feel most people aren't "getting". It's not a single player Castlevania experience. If you approach it with that mindset, then it fails hard. If you have some friends who enjoy old school side scrollers, then give this a shot.
