This is the ideal megawad. Not only emulating the style of the original games, but pushing it forward with new enemies, whole new areas powered by a brand new texture pack, and new design concepts. Level after level of this game took me back with its creativity. There's one early on that starts in a small hallway and, with every switch press, opens up into an ever larger level filled with hordes of enemies. That's a design I hadn't really seen before—this level that evolves and grows as you go through it. Not just opening individual doors, but bringing down entire connecting walls and opening up into a larger space. It's also not even the most interesting level in the game.

Barring some horseshit here and there (the second secret level is far too long for a Doom level! it took like 30% of my total playtime to beat it!), this is just an incredible piece of work. The team has my respect forever.
