About this game
Help Atty and her team steal panties : PANTSU: Atty’s Collection is a casual online single-player collecting game, where you help Atty, Mizu, Sasa, and Rikki collect a constantly growing list of panties in the world. Fill up your collection, earn panty points, and use those panty points to unlock higher levels and more outfits to customize your own member! Brief Story: Atty is the founder of Atty’s Secret Base, which is a secret organization designed to find and collect (steal) panties. PANTSU is a specialized team that stands for the “Panty Acquisition Network, Team Star Unit,” which specializes in stealing panties directly from people to add to the collection. Atty, Mizu, Rikki, and Sasa (with the panda bears) are the main members of PANTSU, and needs your help to collect them all! Game Style: Each of the characters has their own unique style of collecting panties. Atty has a reaction time method of collecting panties, where you will need to press the screen when the yellow bar is within the pink circle. Mizu is very calculated in her approach to collecting panties. Solve “simple” math problems to find a way to collect panties with her method. Sasa's style is based on her ability to manage the little pandas she takes care of. She helps control the chaos that the pandas make when collecting panties. Tap on the circles in order from lowest to highest to collect panties. Rikki’s style simulates the complex maneuvers she makes with her tail to collect panties. Drag the coin through the maze, collect the keys to open the door, and drop the coin into the treasure chest. Collection: Fill up your panty collection in each stage. Each character has their own Legendary panty that reflects a portion of their personality. Mizu, Sasa, and Rikki each have their own variety of legendary panties they can find, so mastering all the styles of play is needed to complete the collection! Progression: Each panty, based on rarity, will earn you panty points. These panty points can be redeemed to increase your level, which will unlock more stages and more outfits for your member to buy. Check the leaderboard to determine your rank in Atty's Secret Base! Character Custom…
