You are the boss, kill the hero before he kills you. You have three attacks in the bottom right corner, click them to use, the hero will sometimes attack you in between your attacks. Kill or be killed. Enjoy! Sorry I've been so slow! I'm very busy, and I haven't felt like coding. (Eventually I will add more bosses and finish the art and other things, but I wanted to put this in the jam now.)
I made all the art except for the background tiles, a lot of things are placeholder art and eventually I'll get around to it. All the sounds are random stuff I found online!
