Really love the concept, but there are a lot of issues to iron out involving the physics and feeling of momentum. I left some detailed feedback for you in the survey. Not to get too down on you, I hope you stick with it because there are some good ideas here for sure.

Thanks for the feedback, its really helpful to get opinions back like this. The game is still in development, and one of the things we are continuing to work on is the fluidity of the swinging. Be sure to check out later updates of the game too, as when we change things like this we like to get people to test them.
