Blue Mirror (SNES)

Blue Mirror is a homebrew game for the Super Nintendo: a puzzle platformer on a split screen. One controller moves two kids at once, a day kid on the left and a night kid on the right, and your goal is to bring both of them to their doors.

The night kid is a reflection. Press right and both walk toward the mirror. Press B and both jump. But each world has its own walls, pits and spikes, so the trick is to let one kid get stuck while the other keeps going.

🧩 How to Play

• Bring both kids into their own doors to clear the level.
• RIGHT moves both kids toward the mirror, LEFT moves both away from it.
• A kid that walks into a wall stops while the other keeps walking. Use it to change the distance between them.
• Spikes, pits and closing gates send both kids back to the start. There are no lives: retry as often as you want.
• Buttons open the gates of the same color on the other side of the mirror.
• Later worlds add ice, conveyors, springs and round buttons that only work while held down.
