Awesome game! Very clever how you indicated which attack type each enemy is weak to. The animations of said attacks corresponding to the arrow key direction is also really great! Very conducive to the quick reactions needed to do well. Once you figure out all the different combinations though, it kinda loses its initial appeal and turns into a "simon says" type game. I wonder if there's a way to increase the enemy complexity over time in a way that also retains that puzzle-solving element...
Again, great stuff! For future players, I got a high score of 23. Think you can beat it? (Probably!)
