Having fun playing this one I really loved the hit-and-dodge mechanism!
1) Increasing the map size & adding the way to let the player know that the brawlers' approaching such as mini map
2) Considering to modify the key bindings
(for example, I think the key "Space" or "Shift" is more adequate for dodging rather than "S")
... might make this game better
But still, this is a lovely piece of art! XD
