About Effective Immediately
A single-player first-person shooter in the browser, set in an office that is falling apart around you. The official submission describes a burned-out worker fighting through a collapsing corporate nightmare to escape before the system consumes him. The game's objective screen reads “Find a way out”; you fire a stapler gun at 2D animated enemies, which the game's sprite files show turning into monsters, and smash 3D office props such as chairs, monitors and computers. The entrant says the aim was a fast, violent, surreal game about losing your mind in a controlling workplace, mixing old-school browser FPS energy with 2D animated characters, breakable 3D props and a comic-book horror style. It was made for the Cursor Vibe Jam 2026, whose rules required at least 90% of each game's code to be written by AI; the official submission lists Codex as the tool. It finished 25th of 945 entries. Free, on desktop with mouse and keyboard; the submission marks it as not mobile-ready.

“I wanted to make a fast, violent, surreal game about losing your mind inside a controlling workplace, mixing old-school browser FPS energy with 2D animated characters, breakable 3D office props, and a comic-book horror style.”Verification notes: Tool (Codex), engine, genre, pitch, inspiration and the multiplayer (No) and mobile (No) flags from the entrant's answers in the official Vibe Jam 2026 games data (submitted 30 Apr 2026; final rank 25 of 945 entries, no award); rule 3 on the jam page requires at least 90% AI-written code. Developer unknown: the jam data gives only the X handle @insomni4_jpg, which no longer exists (checked 4 Nov 2026), and the game page names no one, so the record uses the handle. Team size is not stated. In-game text (“Objective”, “Find a way out”, “Stapler gun”, “You died”) and asset names (enemy walk, attack and transform-to-monster sprites; chair, monitor, CPU and fractured crate models) come from the game's script; the script also contains a developer debug editor with Portuguese labels, which is not presented as a player feature. The game's code loads only its own files and the jam widget; no calls to AI services were found. The jam page's widget counter showed 434 plays for vibejam2026.vercel.app on 4 Nov 2026 (observed; plays are sessions, not players or downloads, so not recorded as a metric). The release date is not stated; the jam submission is dated 30 Apr 2026.
