Vladimir has a keen grasp on the particulars of Doom gameplay and more importantly makes the kind of Doom maps that I heavily enjoy, where you get to pick apart at some kind of Rubik's cube until at last every monster is dead and every passage is completely open. Well, I failed to figure out most of the secrets in the levels. I am assuming there are a lot of timed runs involved, but on HMP the recharge rooms he has spread around the place are usually more than adequate for your Dooming needs. If you don't mind getting bloodied up a bit (or a lot) you should download skePLand and give it a go. It's great stuff.
