I meant that the number of attacks increases with difficulty. It’s ~10% rather than 20% (because the boss doesn’t even appear below 30%). The exact numbers are 30%,50%,60%,70%,80%.
Too much hand-holding.
Rings travel in both directions, so reversing would not solve anything.
Because this way is consistent with cheaper models, which only have two satellite slots. I agree that placing the 3rd/4th slots further out would be better, but there’s no space on that screen.
