Hey! We actually did fit the theme.
If you stop you die
We added a twist to it. When frankenstein stops, he dies, but no one ever said death needs to be the end
While I see your point, again the twist we added is if you stop(move from the coil), you die since frank can't live without it. The die part is just becoming a ghost.
It still focuses on the theme, just not in the "traditional" many expect: An endless runner where if you get hit, you stop and die(die being the game over)
