A whole lot of potential...
I must say, for such a good-looking game there was little to no lag which was a pleasant surprise. And the music was top-notch too.
But The gameplay itself is pretty slow, and everyone has a tonne of health which makes after the first playthrough beating the game again feels painful.
Each character is actually quite fun to play, with different strengths and tactics to make up for one attack button and I found their designs and abilities interesting. But the endings were pretty bad, and they just called attention to a lack of story that I otherwise would have been fine with.
Overall i'd love to see a sequel with some polished writing and faster gameplay.
Some things i'd like to see:
-An option to change the number of rounds per fight, I think the long rounds wouldn't have been a problem if there were only one of them.
-A reason for the fighting to take place, the unplayable one seemed the be the endboss most of the time(except one time I fought him on round four!) and the fact that he was unplayable seemed to set him up as an antagonist. But I have no idea who he is, what he is and why he is there.
The guy named hero seems like an obvious candidate for the main character, and the dude with the scythe( whose special ability rocked btw) seemed like he could be an antihero or rival of some sort.
Blue struck me as a fast-talking irratatingly cheerful theif and the robot dude has "for science" written all over him.
With a good writer this could be a excellent game, as it is now it's still one of the best fighting games for free that I know of!
