Just a note, the D2G screenshots on the store page look awful, like someone ran them through a sharpening filter. In general, GoG really should at least have an option to view full-size, unaltered versions of the screenshots because most of the old games with pixel art get butchered if resized some arbitrary amount. In this case I think the result looks worse than just careless resizing though.

Doing a Google Image search revealed that the game actually looks pretty good.
