Wow, what a bizarre game! The attack and defense stances made me laugh :D
I decided fighting in this game is not beneficial, so I was just jumping over enemies, sometimes holding down W do kinda glide on top of the enemies.
This way all the different types of the enemies you made were equal to me, since nothing could hit me really.
Maybe two pieces of advice:
1) here despite the tileset having tiles 16x16, many of them actually fit when the cell size is 14x14, so changing that would maybe make your game look better
2) regarding the bots just hold the attack position, saying "come and get me"; I think it would be nice to add some animations for the enemies (mainly the red ones) - like they would flash some color and then try to charge you, something like that.
