One last thing! Sometimes when I hit the batteries, I feel like I'm being cheated because I realize that the negative charge is up but I could have sworn I clicked when the positive charge was up. Even though technically I'm sure I actually clicked just as the charges were changing. But that's hard to tell, because that's probably frame synced and I can't see/react frame by frame.
I'd suggest 2 things here.
- Apply the same logic as coyote time here. Have it so that even though the battery has visually swapped orientation, allow it to be treated like the charge is still positive up top for a a few frames. It could be 3 frames or 15 frames. Play with the number and see if it changes how the game feels. Play around with doing that when positives up top change to negatives, or even when negatives up top change to positives as well for consistency.
- Have some visual indicator that a battery is about to change orientation. It could be as small as making the battery wiggle a little bit or pulse in size. It's just important to have some sort of telegraph that the state is about to change.
One or both of those, I think, will add immediate value and improve the game feel in a surprising way.
