Use this software in a well lit room and stay at a reasonable distance from the computer or television screen not to exhaust your eyes. Have breaks regularly: a 10 to 20 minute break every hour and do not play when you’re tired or lacking sleep. Playing for too long or too close to the television screen can make your visual acuity drop.
In some rare cases, the stimulation created by a strong or flashing light when you’re staring at a television screen can cause temporary muscular convulsions or even a loss of consciousness. If you experienced such symptoms, please consult a doctor before playing to this game. If you're feeling dizzy, nauseous or sick while playing this game, stop playing immediately. If these symptoms persist, consult a doctor.
