Good animations and effects, good voice acting. Good gameplay . A little more variety of combos at the beginning would have been nice. It seems a little buggy.
But the speer attack looks and feels very good.
Although it was difficult for me to enjoy it to the fullest. The jump seems a little weak, and a double jump would have been nice when those vertical lasers fly around. but I'm sure that shouldn't be too hard to do.
I also can't tell when I am hit, so I usually die without noticing beforehand. Best add some kind of hitflash.
All in all this seems to be a solid game already. Just a few adjustments and it's good to go :D
