I had a ton of issues myself, and I mean a ton. Still, nothing game-breaking except one glitch at the end preventing me to phase onto some pipes. Had to reload, and actually jump towards my death and phase at the last possible split-second, when I was the closest to the wall, to make it. And no, it was not what I was supposed to do anyway
Overall, one of the best Arcade titles, just because it happens in the Paris of the early 1900, and the devs had the balls to make something unique.
