The level is cleared when the player collects all five comic pages (ten pages in levels 3 and 4, seven reflector shards in level 5). Pickups in the game include health, energy for the player's Pony Power meter, Double Points to momentarily double the player's acquisition of score points, Bonus Time to take several seconds off the player's time spent in the level, and a speed boost power-up. Hum Drum (Level 5): summons Fluttershy/Saddle Rager to slam on the ground.Mistress Mare-velous (Level 4): throws a "hoofarang".Radiance (Level 3): creates a energy cage.Masked Matterhorn (Level 1): shoots a fireball.Super attacks also vary between characters: Super attacks have much farther range than regular attacks (reaching enemies across the screen) but expend "Pony Power" (the energy meter below the player's health bar). The player can also attack enemies with super attacks by pressing the Shift key. Spike/Hum Drum (Level 5): summons Pinkie Pie/Fili-Second to tackle enemies.Applejack/Mistress Mare-velous (Level 4): whips enemies with her lasso.Rarity/Radiance (Level 3): stuns enemies with gem-shaped attack constructs.Rainbow Dash/Zapp (Level 2): zaps enemies with a bolt of lightning.Twilight Sparkle/Masked Matterhorn (Level 1): freezes enemies with her freeze ray.Attacks vary depending on the character the player is in control of: The player can move up, down, left, and right with the arrow keys and attack enemies with the spacebar. The objective is to collect a number of comic pages in a 3D maze-like environment populated by enemies (the Mane-iac's henchponies, includingsoldiers, officers, and captains). In each level of the game, the player controls one of the main cast. The game concludes with a shot of the Mane-iac being sent flying across Maretropolis. Spike collects and assembles the pieces of a broken reflector and uses it against the Mane-iac when she fires her doomsday device. In level 5, Spike frees Fluttershy and Pinkie Pie from captivity, and they help him against the Mane-iac's henchponies. However, soon after they arrive, the Mane-iac captures Fluttershy and Pinkie Pie and holds them hostage at her shampoo factory, and it's up to Spike and the others to save them. The game's story is very similar to that of the episode it's based on, with the Mane Six and Spike being transported to the comic book world of Maretropolis and becoming the Power Ponies.
