Regarding that glitch, as I've said to others it's weird because it seems to only happen to certain people. Would you be able to tell me what specs you're using, I'm suspecting it may be hardware related right now but I don't know for sure, since it doesn't happen to me on either computer i use.
The characters all control the same, the difference is they each have different special moves. I will definitely add a button that skips the entire scene, I just didn't get around to adding that.
Thanks for playing!
