How to Play Cat Mario

Cat Mario (also known as Syobon Action) looks like a cute retro platformer and plays like a practical joke. It is deliberately unfair — the fun is in learning each nasty surprise and beating it anyway. Here is what you need to know before you start losing.

The Controls

Everything runs on the arrow keys. Left and right to walk, Up to jump. That is the whole moveset — the difficulty is never the controls.

Expect to Die

Cat Mario is a troll platformer. Blocks bite, clouds drop enemies, and the safe-looking path is usually a trap. Dying is how you learn the level.

Memorise the Traps

There is no fair way to react in time on your first try. Take mental notes, come back, and route around the ambush you just walked into.

Reach the Flag

Each stage ends at a goal flag. Clearing one without rage-quitting is a genuine badge of honour. Then the next stage does it all again, worse.
