Nice, medium-sized level. I had to play it on normal difficulty because, on hard, it was too much for my aging reflexes. I got a little disoriented since it's not a linear level, but that makes it more interesting. The jumps and flips needed to progress are perfectly accessible for the average player, and as usual, only the final fight is a bit difficult to win. My only criticism of this level is that, given how large and complex the environment is, perhaps they could have added more fights in some corners and a few more alternative passages or secret rooms.The author says it takes 10 or 15 minutes to complete, but I promise you it took me more than twice as long (yes, I'm quite slow).
Good level and very impressive for a first map. My congratulations.
