I like this game and I even tried to speedrun it, but it became a bit irritating experience, because character is not always responding to controls. Edges are a little bit too slippery (but it's not that big problem, it's just a matter of precision). But truly the biggest problem I have when I am trying to speedrun it is dashing, because it's very inconsistent. Even when I am pressing a key the shortest amount of time, character's still dashing at the short or long length randomly. It's breaking the rhythm while fighting bosses and it's messing jumps. But as I said, for casual gameplay, it's a good game.
