Not so bad, I think you like Mega Man games as i do...
SO I'd request a few things:
1. Let the hero get 1 power of the boss when the boss is defeated to keep game interesting
2. Fire Comet (I think you made that off of Nova Strike) should be usable by charging normal strike OR getting hit by enemies and filling a bar.
3-4.Shooting should be chargable, plus dying alot and getting lifes so much, makes the dying something worthles.
5.Your English is bad, but not as bad as some people I've seen, Just keep on learning on it and you'll get better eventually.
