Joyboy is a game that I currently working on with Rindi Games. Joyboy is a simulation game of playing a video game, where the player plays as a boy who is determined to be the best game player in his class. Through Joyboy, I want to remind the player that playing the game is not limited to what is happening on the screen. Sometimes, even small thing such as helping mother can be a part of what makes the game to be fun. I hope through this game, we can ponder the question of the boundary of the game. In this project, I work as the game designer and also the artist.
