I randomly thought about what an XORnament would be; a Christmas ornament that acts like a logic gate? Pun-driven development made me build a small game out of that.<p>No ads, trackers or other bullshit. Built from scratch in plain JS, no dependencies or build pipeline. It's a single html file, so feel free to save it for offline play -- though check in in a few days, because I haven't finished all the puzzles yet.
