A weird bug
I'm not familiar with this game or the moves list, but the computer started doing a move where a power meter showed up on the bottom, and a bunch of dust clouds sprang around him in circles, and the screen turned flashed black behind the characters. When this happened it just kept flashing the background black, the power meter would flash in the bottom, the sound of hitting would play, over and over again. I could jump around, punch and kick, and the timer was still going. But after the timer had run out, it still kept going, also even though I could punch and kick the CPU player his health didn't go down during this time. I wish I could be more exact with this bug, but I'm only taking a quick look at the game.
As far as the actual game goes AWESOME JOB! That pretty much felt like playing an actual 2d fighter, which I haven't done in forever!
