Yeah they basically said that games that hard and frustrating do not get developed nowadays. Guess they just played on the Remix machine cause all other DK cabs were in use.
The cab with Remix had more space around it for the camera man, I think.
That's pretty funny/ironic that they were playing a new game to explain how games like that do not get developed nowadays. And none of them noticed that the stages were different from regular DK? They're probably going to get a few calls from people wondering to to reach those screens, haha.
