EDIT: Just read an interview with the author. Looks like he built the game in just one week. His email and personal phone number were included in the title screen, so he often got phone calls, including from mafia demanding he send them the prizes they won (hilarious things like "shoelaces from Procter & Gamble" and toilet seats). Even though the game was not officially sponsored, the actual show had two rooms filled with letters with similar demands.
