Things to improve:
* with the exception of controller controlls, there shouldn't be 2 dodging buttons for each direction. It should probably be one button dashing in the last direction you moved or are facing (whichever feels better). I would be fine on controller on the trigger buttons though.
* respawns shouldn't happen for a while until after you've killed a mob, at least until you leave the screen. You can't utilize the dodge back at all if the mob is just going to be back where you started your last fight.
Pretty fun, but definitely less hard than the last demo I played of this where the character was slower.
