congrats on making a game!
im liking what im seeing but the ui/ux could do with some work (playing before you've added any written instructions)
some text or something on screen to explain what actions they are taking when its action phase would be nice, better yet moving the wizard and player foward towards the center of the screen when attacking, doing their damage then retreating. would help sell the turn order a bit better, as currently it feels a bit random when you take damage even though its following the turn order that as well as a hit reaction would help figure out how exactly the bullets work without having to do too much guess work/ trial and error.
its also a bit easy, im trying to die and im still winning with 6hp left.
another nitpick, the first time i saw the ending screen i thought i had lost, as "you stand again" combined with the "restart" seems like you were defeated and needed to recover. maybe something like "it was a hard fought battle but you came out on top" and "return" or something to explicitly state that you won.
