At first look, feels like the BEST game for the Jams made on Unity I've ever seen. Nice visuals :)
But yes, lack of sound effects. Also, there is no any Move List - how could I find out a heavy swing on [1] and dodge roll on [Q]?
Random sounds of Jump are not only have different sound volume, but actually a different voices!
Please Keep Up the Great Work! There are too many things to implement and to polish. A way to exit the game, yes :)
Feel free to check out my entry for an example of how the menu flow can be done. That could be useful for You too ^^
