Hi, I tried on Insane mode based on Evilous' comment.
- Felt like my own character's attack quickly reached maximum potency (too early) where I was just wiping out the early screens before anyone could shoot.
- Defeating enemies and striking the bosses is unsatisfying with no hit-stop; flashing upon receiving damage; sound-effects (from what I could tell)
- Seems like your hitbox is smaller than the graphic? The crow's attacks are too narrow I presumed, unless all I have to do is make sure my soul dot doesn't touch the bad dots.
- Control wise, doesn't feel satisfying to move. Its fast but I had a hard time with precise movements. Thumbsticks with gradual levels of movement speed might be a solution; hoping you can think about a way to solve that problem on a keyboard.
