Frontline version.
I was fighting Pumpking on floor 6, and upon killing him and receiving the room score, was killed by one of his Jumpkins before I could dispatch it. The game would continually respawn me, and I'd be killed by the Jumpkin all over again. Disappointed as I was, and lamenting the end of what was otherwise a good run, I progressed through the game over screen, and was greeted by this screen (see uploaded image). The game took then took me to Floor 7, where I was able to continue playing and eventually died (again).
Weird that the floor transition screen was black and white, but I've no complaints.
