The Reality Machine

From publisher blurb: You're a whiz at playing the new Virtual Reality machine that's been installed in the local video arcade. That's why a man named Dr. Telos has offered you a fabulous summer job testing the Virtual Reality games being developed by his company. On your first day on the job Dr. Telos tells you about two exciting games, "Super Time" and "Super Space." Then he asks which one you'd like to try first. Will it be "Super Time" or "Super Space" ?
