Xmas Ducks 2000 for MS-DOS

It's December! And that means Christmas LGR once again. Also clones, and I think they're getting weirder. As for the game itself, Xmas Ducks 2000 is another Lemmings variant at first glance. But then I played it and yep, this one surprised me! Ducks has some fascinating changes, rather excellent atmosphere... annnnd some really frustrating bits of gameplay. So it goes with MS-DOS puzzle games.
