One pet peeve of mine in Doom (and Quake) levels is required damage, because I usually like to end a level with 200/200, and having to do a run across lava after picking up a soul sphere or blue armor is really annoying to me. Luckily, though, it wasn't that bad here.
Doom: Sigil E5M3 - "Cages of the Damned"
Sigil is a new megawad by Doom co-creator John Romero to celebrate Doom's 25th anniversary, taking its place alongside the original Ultimate Doom episodes as episode 5. It features nine brand new single-player/coop levels and nine deathmatch levels. I'm playing Sigil v1.0 on Ultra-Violence difficulty on the GZDoom source port.
