It's difficult to say. I had some problems with gumlines, which you fixed for the most part, and the other problems I had had with them may have been due to my lack of practice. But, if you take away the effort needed to swing, you take away the magic of it! some of the movement mechanics for actually being on foot and jumping seemed to be unoptimized, but that's something that has to be confronted right away, so I bet that's already fixed or in the process. otherwise, it just keeps getting better!
I'm really sorry about not replying so long ago, this comment probably has little to no relevance, as you've either worked out these problems by now or identified them. And, hell, I haven't played the game nearly enough to evaluate it, and I'm not an expert, either.
Awesome work man!
