The idea is of course really nice, kind of sad that the actual fighting gameplay is ruined by a move set that is just too slow and limited.
You don't really use your skill to defeat your enemy, at some point the slowness of your move simply becomes the issue.
I'm also fairly sure that the Hero is programmer to just jump when you press 2, since it starts jumping before the animation even starts.
I guess this could be done on purpose, but it would be nice if it wasn't. Fun to mess around for a few minutes though.
