Thank you for your time and that detailed response! I agree that the melee attack could be better indicated, and I wanted to figure out a way to do that during the jam. As for the camera shake, you're right. In this instance I should have set the camera background to black.
The enemy AI mis-aiming though is actually supposed to happen. I added a randomness factor to the angle it shoots at, and isn't supposed to really aim at the player directly, as the steam is supposed to act as a temperorary area of danger. Though however, I did notice that it will shoot backwards which I was working on fixing but time.
As for juice, you're right! It needs more of it I'd say, and I'm still learning what to add for that.
