Great game! I've been enjoying it for a few weeks now and I'm appreciating all the QOL and balance updates.
I've noticed that the energy voids will sometimes appear mostly off the edge of the screen, making them difficult to see and click. I believe that sometimes they may also appear entirely off-screen or possibly behind the UI buttons for shield boosts/volleys/etc, as there have been some very long periods where I can't seem to find any at all.
