cool game, i personally am a shit typer so it doesn't really hit home for me, always with those dam typos T_T, managed to make it one lap by just using the basic "fast" "left and right" but then i tried to use those word markers and like i at some point always started going the wrong way :P
i managed to finish with 6M 45 and 42K points,
one thing to note is that the words on those points stay the same and so one just needs to memories them than actually type to get a good score.
