The visual level design here is mostly similar to Plutonia and its unofficial sequels PL2 and PRCP. But it is by no means a gameplay part, since for example the gameplay in the first maps revolves around ammo shortage with not so much opposition (although it was tight in places, I admit), while the latter maps are somewhat reminiscent of slaughterwads with a bunch of ammunition and opponents.
The same applies to the size of the maps - the first ones can be completed in 6-7 minutes, while the last ones takes 15-20 minutes to complete. Although this could be explained by a kind of progress, despite the fact that even MAP12 (the first map in wad) is not a walk in the park.
I am not opposed to forced pistol-start (maybe even for), but usually if the levels should be completed in this way, they should be better balanced, as the ability to store things from previous levels is discarded.
And again, I repeat as previous speakers - perhaps some arch-viles were even superfluous. This is especially noticeable when you go through the same room several times.
Mostly enjoyable set in vein of "Plutonia but harder" and with larger fights. Visuals are often minimalistic, with combat being the focus of making the maps interesting. Expect plenty of Viles to resurrect what you kill and forced pistol starts on every map. 3/5
