Mario Bros Save Princess

Grab a friend and storm Bowser's castle together — this retro co-op platformer puts two plumbers on a princess-rescue mission.

Right from the first level, Mario Bros Save Princess feels like a love letter to the 8-bit era. You and a buddy each control a plumber — Mario uses WASD, Luigi (or 'Louis' as the game calls him) gets the arrow keys. Jumping feels exactly as tight as it should, and the invincibility power-up (S or Down arrow) turns a desperate escape into a glorious stomp-fest. I kept forgetting which button was which at first, then it clicked. There's a moment in the castle stage where a row of firebars syncs up with a moving platform, and you'll either time the double jump perfectly or watch both plumbers tumble into the lava. Co-op isn't just simultaneous play — you can save each other by clearing enemies, and the shared life counter means you'll actually coordinate instead of racing ahead. It won't replace your memory of the original arcade, but as a free browser game for a quick lunch break with a friend, it does the job. The pixel art is charmingly blocky, the music loop is catchy without being annoying, and the difficulty ramps up just enough to keep you hitting 'restart' without throwing the keyboard. If you've got five minutes and a second player, this is a solid pick.

Use invincibility (S or Down arrow) right before touching a firebar to bust through unharmed. Coordinate with your partner: one clears ahead while the other grabs coins. Don't hoard power-ups — the second player can rescue a downed plumber if you share timing. Watch the moving platforms' rhythm; they pause for a half-second at each end. Keep both characters alive as long as possible; the shared life pool disappears fast.
