I have nothing but praise for this double header of demonic delights, I loved both DK and DD as a kid, and I still love them as an adult, they run beautifully and the resolution is fantastic once you've stuck it in hi-res. DK was a triumph during Bullfrog's heyday, the difficulty builds gradually as you go through the game, and even as an adult I am still challenged by it as much as I was when I was a kid. Cannot recommend this title enough!
Right I'm going to start by saying I love, love, LOVE this game and always have, and it's exactly as I remember, trickier the further into the game you get, it's humorous and witty, and the same cheats exist to bail you out if you want to bypass the more challenging elements like a wuss. However on quite a few occasions now I have experienced the game glitching out on me, or just crashing altogether. You will occasionally get staff members or patients coding getting stuck, meaning their physical form is where it should be, but a second version of the same form stuck in one or two squares on the map, meaning you either have to reload from an earlier point in the game, or restart the level completely, which is just irritating. Granted these things were part of the game in the 90s as well, and it was by no means bug free, it's just hampered my playing experience more than it had when I was a kid.
