SCREAMING JEFF: MONDAY SURVIVAL Jeff is a middle manager. Jeff is having a bad Monday. Jeff is now flying through the office on a rolling chair. Jeff needs YOUR screams to survive. SCREAM into your phone to launch Jeff upward. SHUT UP and gravity does the rest. Dodge the deadly pipes of corporate doom — each one labeled with the office horrors we all know and fear: JIRA, SCRUM, KPI, OKR, TPS reports, and mandatory 1:1 syncs. HOW TO PLAY: - Scream = Jeff flies up - Silence = Jeff falls down - Hit a pipe = Jeff gets "restructured" - Survive = Meetings dodged FEATURES: - Voice-controlled gameplay — no buttons, just raw vocal energy - Retro 90s pixel art with CRT scanline effects - Jeff's mouth opens wider the louder you scream - Hilarious milestone messages as you progress - Death messages from HR that hit too close to home - Pixel explosion of office supplies on every failure CAREER MILESTONES: - 5 meetings: Performance review pending - 10 meetings: Promoted to Senior Jeff - 20 meetings: Employee of the Month - 50 meetings: Jeff becomes CEO WARNING: Best played alone. Your coworkers, family, pets, and neighbors may not appreciate your dedication to Jeff's survival. Not responsible for sore throats, noise complaints, or involuntary career changes. Screaming Jeff — because Mondays deserve to be screamed at.
