Well, if you don't wanna add a combo, you have to add at least, special attacks (without them fighting games - not fighting games,only some sort of a boring bullshit > -<), because the two punch for each character - not a good thing
The music in the game is not bad, and even I can say that this is almost the best thing in this game =D
design of the characters though not finalized, but still not bad.
but I hate that fucking Cyclops - he has a gun! it is unfair, I think >__<
