Thank ya, I unfortunately didn't have time for the introduction pattern. And, I forgot to add an Angel death sound effect. They have a short particle effect, but nothing auditory. Also, the Angel that is going to attack you starts pulsing red and moves to the center of the screen. When, it pulls back you'll need to move. But, they are a little too fast.
The difficulty and visual cues are definitely going on to my list of post jam goals
