Listen Chucho is not gonna lift a single finger if you guys stop fucking his threads like no tomorrow, So the less Hissy fits we get the more (maybe, MAYBE) completed characters from Chucho we'll get.
Most of Interactive Stages depends on the Coder that knows the line of code for it like knocking a opponent to another part of the Field for that you need only the code and the sprites for it if the character can trigger it.
