What other game could shrunk to 1D ?

I think the experiment of squeezing tetris in 1D worked OK.
Now I was thinking, perhaps I should take another game and squeeze it into 1D... just for the fun of finding a reasonable mapping of operations and concepts :D

I was considering perhaps Mario, since it is a total classic and the gameplay is kind of linear already, but perhaps puzzles would be more interesting, like sokoban(?).

Any suggestions?
