A really boring "slaughtermap" sort of map with a not very good layout and broken teleports. Played it on vanilla doom and doom+ exes on dosbox, it plays fine. Also, is E2M2 have an exit? I didn't want to know because i've get bored while playing at it, sorry.
Despite working alongside Billy for a few years now, and being a big fan of what he does, I hadn't gotten around to checking this out. Turns out I was doing myself a disservice! This is a lot of fun to explore, with many twists and turns, and some pretty intricate secrets. A very strong start for him, but I can see where he's grown since. In particular, the progression and distribution of weapons can lead first-time players to be quite underpowered for a long time, depending on where they go first, and my initial playing experience suffered as a result. Likewise, the way secrets are woven through the map and partially limited based on progression makes for a great story telling device, but does rather impede your chance to experience everything if you don't know when things are available and what will stop them being so.
Saying all of that, the game play is generally solid, the additional textures, artwork and music choices are all on point and the level looks very nice, so I'm more knocking a star off because of the open-ended progression not working out perfectly for me on my play through, than anything else. Well, that and I know he's gone on to bigger and better things, of course! Great stuff, highly recommended.
