A rail shooter, with a difference, replacing bullets with pheromone shots, and enemies with giddy love-obsessed school girls. Every love letter and advancing kiss drains your energy! Repel them while upgrading your power ups and take part in outrageously lewd mini-games to find your true love!
Players take on the role of Houdai, a high school student who becomes the center of attention for all the girls at his academy after being shot by a cupid's arrow. The core gameplay loop involves using the targeting cursor to fend off the advancing, love-struck girls by shooting them with pheromone shots to keep them at bay and maintain Houdai's energy levels.
The shooting mechanics offer a good amount of versatility. Players can use both normal shots and "Ecstasy Shots" which deal more damage but consume more energy. The game also includes a dodge mechanic that allows players to evade the advances of the girls. The targeting reticle is forgiving, but players can challenge themselves by aiming for the most sensitive areas to earn higher scores.
The game features a variety of levels set throughout the high school campus, each with unique layouts and enemy patterns. As players progress through the story, they unlock new areas to explore and new girls to encounter. The ability to choose different routes and locations in the level select screen adds to the replayability.
Between levels, players can spend points earned to upgrade their pheromone shot power, energy capacity, and other helpful abilities. Additionally, players can unlock new outfits and accessories for Houdai, allowing for a degree of character customization.
In addition to the main rail shooter gameplay, the game includes a variety of minigames and alternate modes. These include rhythm-based "Doki Doki" sequences, hentai-inspired "Ecchi" events, and a "Score Attack" mode that challenges players to achieve high scores on specific levels. These supplementary activities provide a welcome break from the core shooting while also offering additional avenues for players to engage with the game.
