Hmm... that char is still pretty good, but it has a few elements that I think need adjustment.
I don't think that when he turns invisible he should be completely invis. It doesn't look right.
It should also take him a little longer to activate a power like that its too fast so you can't stop him.
The projectiles are too fast. I saw that he spammed projectiles.
I hate spammers. Makes the battle boring.
Other than that the sprite work is pretty good. 8)
I can't complain... yet.
