Gameplay
Although both characters have different weapons and learn different attacks, they are functionally identical. Their primary short-range weapons have three levels and are improved in range by acquiring grey cats left by defeated enemies. Both characters are also equipped with thrown weapons from the beginning (which decreases money as you use it) and can acquire bombs by purchasing them in stores or by winning them in mini-games.
Each character can learn four Judo abilities which are functionally identical between the two characters. Level 1 Judo provides an animal companion for the character which they ride and can use to ram into enemies. Level 2 Judo releases an attack that can damage all enemies on the screen. Level 3 Judo gives the characters the ability to fly temporarily. Level 4 Judo unleashes a powerful repetitive attack.
Most stages are separated into two sections. The first section is centered on town exploration where players gather information, buy items, learn special Judo attacks, play minigames, earn money, etc. One of the most notable mini-games available is a recreation of the first level in Gradius, but also includes games such as air hockey, trivia, dice games, and even a lottery.
The second section of each stage is a platformer section where the players fight through minor enemies until they reach the end and defeat a boss. In two-player mode, the characters can work together by having one ride the other piggy-back style. The character riding controls the attacks, while the character being ridden controls the movement and jumping. This can simplify areas with large or awkward jumps as it only requires one player to land successfully.
After each stage is completed, a small scene occurs furthering the mostly simple and light-hearted plot, and the next stage is revealed.
