I remember when I was thinking "man, I should learn how make characters because I doubt anyone else would make the werehog" then seeing him in like a day later, good times.
So The werehog is a great character, I like how his ability to stretch his arms isn't lost as I was thinking about how hard it would be to convey that, but the grapple punch does a perfect job representing that along with the ability to use it to stop and keep all of your momentum when using it, making it really versatile when platforming or speeding through a level.
The Were-Claw in the in the air is neat, but the hit box always felt a little to small, like smaller then the piko hammer, and it's use feels much more limited, only thing I could suggest is take make the hit box bigger and probably change the sprite of the move to reflect the bigger hit box, but maybe it's just a me issue.
Were-Spin is also nice move to make up for the lack of a spin dash, and it being fully controllable is a good way to make it useful and more unique then just a spin attack even if it's small.
I do think the werehog is lacking a bit, it might be the were-claw bit or maybe I was expecting more combat options, but that's tricky to place in a game like srb2, but cacee also did manage to pull something like that off, so maybe he could use a punch attack like that, but that might be hard to pull off when his in his running stance unless the attack changes depending on what state you are in.
Despite the small issues I have The Werehog still a very fun character with good utility and I'm looking forward to his update so I can play him again, due to his now bugged grapple punch, take your time on that I know it will turn out great.
