It's a pretty solid port all things considered, but it's lacking on any interesting settings like the Doom 64 port had. A recent update added the ability to download some curated Doom 1 & 2 mods (including the level packs that made up Ultimate Doom and John Romero's Sigil expansion) is pretty dope though.
The original 3 episodes for Doom still rip and tear, but it took me a while to realize I don't PARTICULARLY love the bonus episode Thy Flesh Consumed. The design difference is pretty huge and it really sticks out.
