PolarityFlip

Two boundaries. One charge. One finger. PolarityFlip is an arcade runner about a charged sphere threading a cave that never stops moving. The ceiling is positive, the floor is negative, and your sphere is always pulled toward whichever boundary isn't its colour. The only thing you can do about it is press. Press and you repel, hard. Release and the pull takes back over. That is the entire control scheme — and it is enough, because the corridor narrows, the speed climbs, and every so often your charge flips. THE FLIP A countdown warns you. It does not help as much as you would like. The moment your polarity inverts, pressing does the opposite of what it did a second ago, and you have a fraction of a second to unlearn a habit you just spent half a minute building. The cave stops turning and opens up a little to give you room. You will still hit something. CHARGELESS BARRIERS Grey slabs drift mid-corridor carrying no charge at all. They do not pull and they do not push — they simply sit in your way. Over or under, your call. They vary in size, they arrive on no rhythm you can memorise, and they never land on top of a charge flip. That combination would be unfair, and this game is only ever unfair on purpose.
