Pretty good for your first
You have a very cool art style. NEVER CHANGE YOUR ART STYLE!! IT'S REALLY COOL! I liked how the enemies could hurt each other. Finally! A game that follows the laws of logic! :p Just a little more combos would be good, and it was really annoying how whenever you got attacked, you turned the other way. Also if you hit the A button too much, the guy just keeps on slashing even if the monster is dead. I took a lot of damage cuz of that. Try to fix that by being able to cancel an attack by moving the other way or jumping. I know its difficult to create a game as good as this, but just keep that in mind. And definitely make another one, and KEEP YOUR ART STYLE!!! NO MATTER WHAT!!! you should also allow people to name their character.
