"Alone Time" uses virtual reality to convey the influence of virtual friends on children. Since many people were the only one child in their family, it's interesting to bring imagination to life, highlighted by the multiple cameras in the game that show the difference in perspective between a child and an adult. The author hopes to bring the virtual character in the player's imagination through his own experience, combining children's cognition and feelings for strange things. Preserve the author's childhood memories in the form of a virtual model, and bring players with different backgrounds a unique experience through the interaction and immersion of virtual reality.
