This was really fun, the difficulty actually progressed which is nice and the different worlds having their own gimmics and atmosphere made it interesting to explore. I really liked that the hub world/area is really small and compact making backtracking not as big of a choir and there's plenty of moments I really thought where cool/fun like the Cyberdemon trying to snipe you at the top of the hill in Mountain of Doom and the eerie tone of Human Depot with it's dark blue rooms filled with former marines. also for those who are wondering what the songs are: World 1: Dark Imprisonment = Map10 - Equinox (Doom II) World 2: The Underworld = Plasma - Duke Nukem 3D World 3: Mountain of Doom = Map12 - Equinox (Doom II) World 4: Blood's Lair = Briefing - Descent 2 World 5: Human Depot = SUPER Slow Evil - Icarus: Alien Vanguard (Doom II) World 6: Hell's Garden = Slow Evil II - Icarus: Alien Vanguard (Doom II) World 7: Highway to Hell = Dracoid Ruins ~ Battle - Lands of Lore 2 Red Symbol Maze = Map20 - Alien Vendetta (Doom II) Hell Tower = Secure Place - Resident Evil 2 Inside the Tower = MAP31 - Hellcore (Doom II) Top of the Tower = Stage Boss - Gradius V Boss 1,2,6 = VS Boss - Mega Man X8 Boss 3,4,5 = VS Sigma - Mega Man X8 Boss 7 = VS Lumine (The Second Form) - Mega Man X8 Ending = Huline Temple - Lands of Lore 2
