Thank you Loktor for playing our game!
Right now we are working on the movement and jump since this is one of the most important parts in our game. I've been looking through some videos to get some ideas but will try to make this as smooth as possible ^^.
Jump after grapple is definitely on our to do list. After the movement update we will work on making the grapple more smooth and interesting, since it should resemble a rope and those don't usually go in a straight line.
Thank you for the feedback, we really appreciate it!
