As the in-game hours to complete the mission tick down, the time of day changes, and so do several of the stages alongside the enemies present in the game. In many cases, this can even change the stage's boss, and may also affect the reward the player gets for defeating the boss.
At the end of a stage, the total time to complete the stage (compared to the record time), the total prinnies dead for that stage (both in the stage and against the boss) and the collection of the lucky dolls is tallied up. This gives the Prinny a rank falling between D to S. Some achievements are earned by either having a fast time or high rank.
The Prinny has various moves utilized in platforming and combat. The Hip Pound is the primary method of stunning, where the Prinny drops on an enemy. Hero Prinny can also double jump to reach higher platforms. The majority of attacking in the game is using the Prinny's swords for slash attacks. By performing a basic attack in midair, the Prinny can also perform a long range aerial attack. Holding the circle button allows the Prinny to spin to avoid most attacks when he glows blue. Pressing left or right during a spin allows him to dash off, making him move faster. Should the player press down during the dash, the Prinny will slide, which also allows him to temporarily become invincible. However, spinning for three seconds or more will cause the Prinny to become dizzy and leave him vulnerable. A Prinny Raid attack becomes available after losing all 1000 lives and starting a new game. The player can sacrifice lives to perform a screen-covering attack of exploding Prinnies. If necessary, suicide can also be activated.
