DROD 2.0 Edit
DROD 2.0 is the first engine version to be used in a commercial release. And even though you had to buy DROD: Journey to Rooted Hold to play the official hold included in the release, the engine itself was still free and you could use it by downloading the demo version of the game, which, however was limited to only one room style.
DROD 2.0 runs at 1024x768 resolution and had all graphics remade from scratch. That also meant that the old room styles from DROD 1.0 could not be used, instead the engine features 3 new styles (see below).
Spiders and tar babies now can face 8 different directions. Also, since there's no more palace style, spiders are now only visible when they move or when they're close to the player.
