I think I explained this a bit better/more thoroughly in my review, but to sum it up, the movement system is very committal while the obstacles are punishing. In order to perform well at that, you have to deliberately avoid being distracted by the right side of the screen... which is really the side of the screen I'd rather focus on, lol
Edit: just want to add that it's not the end of the world or anything, but I just didn't expect this to be the kind of game that I would swear aloud during. Those games definitely can be fun, I fucking love Dark Souls for example, but I wasn't expecting it from this game and I tend to favor the H over the Game for H games anyway
