I've only played Bal's map so far, but it is excellent. Tremendous attention to details. I officially suck at finding secrets, though, as I didn't find a single one. A whole City of Bal episode would be amazing. 

Posted my reviews so far in the wrong thread but long story short, these maps are pretty amazing and I'm having a really good time playing through them. 

There are some real masterpieces in this pack. I was blown away by Strideh's maps. They're some of the best that I've ever played and they pretty much combined all of the best aspects of the game into them. Not only were they fun to play, but they were beautifully designed. Instantly one of my favorite mappers and I really hope that you make more in the future.

Ionous - I very briefly watched you stream a bit of you building this map and I'm glad that I finally got to play it. You managed to fit a lot into a tiny space including a pretty cinematic boss fight. However, I don't think that you can make something that I won't enjoy and I already knew before going into this that I was going to love it. Can't wait to catch up on your other maps that I've missed recently.

Bal - I can't really add to the praise that has been sung about your map. It's great and you already know that. It has a lot of the good game play elements that I've learned about from hanging out with the pros and moreover, it's a treat for the eyes. I usually don't ever use cheats before running through a map at least once but the second I spawned, I had to noclip out of the playable area just to soak it all in and appreciate the view. I also liked the little Easter egg that you put in at the top of the highest building. I kept wishing that the map was longer and not constrained by space or time limits.

Scampie - great base map and fitting for the season. I liked the connection between the boulder and the shootables. I also liked how you started off with the Shambler cave and I thought that the backtracking made for good use of space.

Krampus - I'm not able to guess who this is based on the map style although I have a few ideas. I saved this for last aside from the secret map and to me, it was another perfect map. Not only was it fun to play, but I really enjoyed looking at it. This is the sort of map that captures exactly what I love about smaller maps. I liked the secret poem as well.

Negke - still have to play through this but I took a brief look at it and it was a pleasant surprise especially after having just played your Doom maps only last week. I still wish that you'd make more Doom maps but I'm looking forward to seeing what kind of changes that you made to this one. 

Thanks for the kind words. The boss battle seemed to take a lot of people by surprise, which is what I had hoped for when conceiving it.
