i like your color choise. and the movement is very smooth. cool game idea with switching the characters. choise of music is also good.
i would loved that if the enemys hit you once is not an insta kill. maybe add healt in some way? and healt regeneration over time?
also because the sword and arrow animation is very long, the player needs to time that very good, otherwise he will get hit and is dead.
i used also the tiny swords assets.
