Press the green flag to start, arrow keys to move. The enemy is capable of performing every single action you can, including glitches. Trying to off-screen the enemy won't work because I wanted to make it so you cant back out of a fight with it. The code is %100 by me, it took 3 hours (most of the movement code was in my physics engine sprite from 4 months ago). I implemented lists so you guys can use the code in a way that lets you program the enemies actions, though you do need to edit the main code to do it.
I honestly can't believe I was able to make this, and in just 3 hours!?!?!
