Downloaded and playtested it on Hurt Me Plenty with Zandronum 1.0
Technical:
The starting area has a switch which does not raise with the starting area floor, causing a HoM. easily patched by giving it the same tag as the starting area.
Gameplay:
Reminded me a lot of Chillax, which I didn't like.
The start caught me totally by surprise and there is no way to counter or prevent it. This creates a scenario where only a previous humiliation can help you, which I think is very bad for gameplay. Once I died and restarted, I had no particular trouble taking out the hellknights, although it was still a tough fight. After that, found me totally surrounded and outgunned, unable to make any headway in a pistol start. I died 5 times in a row within a minute or two, out of ammo or totally cornered.
I have no idea how the map continues further... I saw huge monsterclosets waiting in Doom Builder, full of rows and rows of monstrous, slaughterous, spam fodder. Something that didn't excite me.
This also comes down to personal taste, I rather be bagging for ammo and health fighting 3 mancubi, then spamming a BFG until 50 of them die.
Anyway, I hope that my humble bug report helps you fix that one naughty sector and good luck with the rest.
