Pros:

very cute Mario Map, would be nice for younger players who scare easy, the jumping up to break the ? box was nice, you should add more of them.

Cons:

was a little hard to get threw because a lot of the gates are more like solid walls with no switches or leavers to open them. A lot of the doors are useless, trying them all just to see what opens and what doesn't. A hidden passage behind the painting it nice but honestly I didn't even have a clue that was a passage till a smoker grabbed me and dragged me inside it. Maybe a hint or something saying its there would be better, and less useless doors, when I saw the big door with a lock on it, I thought i needed a key to open it and advance to the next area, had to use no clip more then once to get to the place you had the ammo and then to the final castle in the map. 

Conclusion:

It's a nice idea for a campaign just a few tweaks on the first map, and lol, maybe not spawning into a room full off zombies while the computer bot run to the second safe room 50 feet away and leave me fighting the zombies by myself. Then after I closed the safe room door the campaign begins all over again. 
Since your asking for ideas on other maps for this campaign maybe more themes from older video games like this 1, like Zelda for instance

Pros:

nice campaign, loved all the stuff you have to do to advance plus all the helpful hints you get, the lighting was perfect and in all the right places

Cons:

a lot of stationary zombies 15-20 to a room in almost every room seemed a little much

Conclusion:

Good job, good campaign, will play it again

Pros:

very good map

Cons:

nothing i can point out in details

Conclusion:

overall I gave this map an A, loved the lighting lol, nice to be able to see where I'm going this is a campaign I will play again 

Pros:

Not to overwhelming, loved the Dance Club, lol wanted to stay and listen to the whole song. Good campaign and decent to get threw

Cons:

3 tanks just in the first level I thought was a bit much, avoiding witches was almost impossible. the second level was kinda weird because of the floor that seemed to be made of chicken wire and I- beams a little overdone when it came to the amount of stairs you included

Conclusion:

Not to bad, would have to give this campaign a high C to low B average

Pros:

Very good campaign, nice layout, map I will play a lot

Cons:

none that i can see

Conclusion:

Enjoyed this 1, you did very well

Pros:

 I give it an A, NICE JOB!!!

Cons:

None that I can see :)

Conclusion:

Incredible Map, Reminds me of when I was in the Haunted House at Disney World. So far out of all the maps I have downloaded, I've played this 1 the most.
