What I appreciate about this mod is that it is actually trying to do something different with the gameplay. It illustrates the versatility of the Wolf3D engine. Next to that, the graphics are fantastic and really create a tense mood (and it's not the only thing that creates tension!). I definitely recommend trying this mod out. It's challenging for sure, but it really tries to do something different within this engine, and that should always be encouraged.
