After School Simulator is an iPhone game developed by Masashi Kamiyama. This free game falls under the category of Games and offers a unique blend of Japanese high school simulation, open world gameplay, and rogue-like action shooting.

In the game, players take on the role of Yamada, who is on a mission to solve the mystery behind the appearance of monsters from another world. Yamada becomes entangled in an intrigue involving an unknown organization called 'GAFA'. By checking a statue in a school, the world transforms into another realm, where players must find and defeat powerful bosses.

Before facing the bosses, players can search for treasure boxes to obtain power-up items, engage in battles with weaker enemies, and level up their character. However, as time progresses, the enemies become stronger, adding a challenging aspect to the gameplay.

One of the standout features of After School Simulator is the ability to customize your character freely by creating avatars. Additionally, the game offers a wide range of achievements to unlock, providing players with additional goals to strive for.

It is important to note that the in-game localization has been done using Google Translation as a short-term development solution. The developer plans to improve the localization in future updates. Despite this inconvenience, After School Simulator promises an engaging and evolving gaming experience, with main missions, sub missions, and continuous updates adding new features to the game.
