Syobon Action (known as "Cat Mario" or "Neko Mario") is a Jump 'n' Run Game parody. The traps are different from what you would expect from a jump and run game. Skill and a bit of imagination are needed and nerves of steel because it can be frustrating at times (which makes the game so addicting).
The challenge is to beat the game by loosing as few lives as possible.
The game includes the original four levels of Syobon Action with a few differences (new traps), so if you played the original don't be "shy" and play it because it will still be able to surprise you :).
The original freeware version was developed by ちく (Chiku) (http://www.geocities.jp/z_gundam_tanosii/home/Main.html).
