hmm...
...I think you shall be glad, cause this is the only allyway copy i have tryed on NG so i gave you 5 because i love those games.
But put som more effort in it, maybe som power-ups, more different backgrounds, and stages, maybe som extras, or if you can manage som time, then you can make it with a turnament, or something, good so far, but please upgrade it abit. good lukk
