So, I'll give you some feedback. You did a good job on the map. Everything works. Zombies don't get caught up on anything and I didn't find any death barriers.
The map is kinda boring after a few rounds as there's nothing to do except kill zombies. If that was your intention, then ok. Unless I missed a door that leads to other areas, and there's an EE that I didn't find. Overall though, you did a good job.

Don't be shy, LEAVE A COMMENT! Let me know what you think of the map and any bugs you may encounter along the way.
