I enjoy this mod. For the short time I've played with this character it's been nothing but fun, and the moveset works wonderfully. It seems very well thought out, and there's a flow you can get into once you master the moves you have at your disposal.
A few things I'll say is that, for one, the counter displaying how many charges you have left should probably be moved above the charge meter so that it looks less awkward. Another thing I've encountered is a bug which leaves JMS stretched out when using the stomp ability, not sure why this happens.
Something I don't really understand is why the charge jump doesn't hurt enemies. I feel like it should, since the rest of the charges do so.
Otherwise, I'm really looking forward to the future of this mod. Good luck on your coming endeavours.
