Pros:

-Custom content/powerups
-Gnome Chompsky can talk, yay
-nice setting and environment
-some interesting events
-many witches
-many explosives

Cons:

-some nav problems i think
-map layouts sometimes a bit confusing
-powerups
-no "real" finale

Conclusion:

All in all it was a decent map with a cool setting and custom content, but personally, the healing sparklies were the only thing that had a noticable effect on gameplay imo, or maybe I used the gnome the wrong way. Other than that, making your way to the tower and realising that there will be no epic battle in and on and around the tower was a bit anticlimactic.

Also, I think you should add more hints on where to go. It really took me a while to realise that I have to climb the crates in the hangar in map 2 and I completely got lost in map 3 at the part with the dark room full of stuff and the sewertunnels. Eventually, the bots were bored of me looking for a way out, so after 5 mins they decided to run off, trigger a tank and die, so I was all alone and lost in a dark room.
