Very cool concept fight. Very difficult concept fight! This boss has a pretty hefty move set and they're all animated beautifully, it was definitely a treat to look at. The attack was satisfying to use, the range and effect just felt good together. Unfortunately, I wasn't able to defeat the boss, he kept killing me in phase 2, so I put the game down for a bit, but I'll go back and try to kick his ass again later!
Some areas where I struggled
1. The feedback on the player being hit wasn't enough for me, I found that I kept checking my health bar in the upper corner to see if I'd been hit or not, and I was never quite certain what the enemy attack hitboxes were because of this.
2. I'm pretty sure I got the hang of avoiding the lightning bolts, but the player's very quick movement and acceleration speed made moving between the bolts a bit finicky which made this attack feel stressful each time even though I understood the mechanics.
3. I think a better telegraph on his long-range dash would have helped with the second phase. I think there might have been a screen shake when the dash started, but it didn't feel very consistent and so I never knew quite when to jump. This paired with not really understanding the attack hit boxes made this particular attack feel very punishing.
Anyway, I'm not one to shy away from a challenging boss fight, and at least the run back to him is short.:D I'll go back in later today and see if I can take him down, but if you have any tips or tricks, I'd love to hear them!
