Pros:

-Fun!!
-Original
-Hard but not impossible
-Replayable

Cons:

-Spelling and grammar issues
-Pointless tunnels on far edges of map?
-Needs more detail (In-game and non-game) Some Examples: 
*This page needs a better description
*Addon itself needs pictures (Loading Art, Addon pic)

Conclusion:

I really like this map. The original gameplay and difficulty really appeals to me. It has a high replay level due to the building mechanic. However, you need to fix the grammar and spelling issues in it, as well as add more detail. (Specified above)
