At the beginning of the game, players can select which aging impairment they want to apply to the avatar. The impairment options include: visual, audio, muscular control and memory. Once the impairments have been selected, the player is transferred into a residence, where they need to perform ordinary tasks and experience how the impairment affects their capabilities.

KAMK health care personnel compiled the teaching content for the game with help from students. The students studied different aging-related problems and designed a set of tasks that would demonstrate resulting impairments through virtual reality. The information about different age-related impairments was also written and included in the game.

Simppeli Aging uses an elderly resident created for a previous educational game. VR functionality was designed for the game that included all the visual-and motion-based feedback systems for different aging impairments. The descriptions of different age-related issues were written by KAMK students and implemented in the game in both the written and spoken form.
