Just incredible, it was really nice to play, and I loved discovering the differents pattern you incorporate.
It is really incredible to be able to create a rhythms game like this one in such a short notice.
The only things I see you could improve, was the fact that the cars did not have any sound, and beats to it (And I didn't really understand what was the manholes)
But keep the good work, I'm sure you could wrap it into a nice little game, that would have the same feels as Rhythm Doctor ! Looking forward to it !
