1. Actually giving an option to exit out of a match straight out of the pause screen. It would be a lot easier than having to remember which F key does it. Heck, if you could even put text at the bottom right saying "press F-whatever to quit match," that would be nice.
2. Is there any way we can get a training mode? Even if it's just turning off cpu movement/actions, that would be really handy.
3. How about an option to turn off stage hazards? Even if it only removes the hitbox, that would make a lot more stages competitively viable.
