That was really fantastic
Keep up with this and maybe just maybe you'll be as good as earthworm Jim!
The sprite control was fa-nominal and the background was moving everywhere making your eyes glued to the screen. The only back-down is the SFX (Sound effects) because at some parts you would here 3 other people screaming at once along with attack blasts. Clean that up a bit and you'd be great!
I can't wait to see your other wok, nice plot with the Naruto crossover!
