The Monastary of Korax ver1.0

A pretty nice map with some nice detailing like sector furniture but ruined by some pretty bullshit parts like missing keys (at least, i didn't find any during my play nowhere) and some parts looks to be broken like a way to open the exit door, also why putting a wyvern already roaming at the start? It's like somebody put already 2 spider masterminds already at the start of a doom map, pretty much a dickish move imo.

Very uninteresting map in which you navigate through mostly boring, square rooms finding various keys and humping various walls. The combat is very low-energy (even on difficulty 4), mostly just ettins. The climactic final fight is just two chaos serpents you can easily walk past into the exit portal. As I said, the level design is almost uniformly square and uninteresting. The castle is at once trying too hard to be realistic (many square rooms with beds and tables) and failing to be realistic enough (very low-detail). This is pretty much the exact opposite of good level design in Hexen - bizarre, abstract, devious level design that still feels atmospheric and real due to the use of detail and architecture. Furthermore, this level's idea of a puzzle is hiding a key behind a completely random wall whose texture is slightly misaligned. Absolutely atrocious.

The idea proposed by another reviewer that this will kill "a couple hours" is completely absurd. It takes ~15-20 minutes to complete, max.

It's fine, but why did you put the rusted key in a secret? It wasn't worth the trouble to find it.
