I had a great time with the 1st map, loved the visuals especially with the orange light coming off the lava and the ornate details. Combat was good too but a few places had cheap "monster teleporting in right behind you" moments that were a bit annoying. Overall thought a great map with some very original and neat ideas in it :)
I forgot to record a demo sadly but managed to do it on medium on my 1st try and it felt very balanced.
The 2nd map I didn't like so much, again it looks great with a very original take on the tried and tested ikbase set but the combat felt wrong and a bit dull in most areas. I did remember to make a demo of this one (and you can laugh at my n00bish death :D)
