Ever get the feeling your boss is a deranged puppet? Like they might be out to get you? A maddening, questionably human monster who will literally be the death of you?
Welcome to Mr Magpie’s office, where that nagging feeling might just be worth listening to…

Behaviour Interactive and Gambit Digital invite you to play Mr Magpie’s Harmless Card Game. Don’t be fooled by such twisty corporate-speak, though…. Harmless this very definitely is NOT. This single-player trip into corporate horror is available as a demo now on Steam.
What is Mr Magpie’s Harmless Card Game?
Mr Magpie’s Harmless Card Game is a corporate horror deckbuilder from Giant Light Studios. You find yourself trapped inside a bizarre, eerie corporate office. Working here is literally hellish.
Guided by unnerving hell-muppet middle manager Mr Magpie, your job is to flip cards, blending Minesweeper-style deduction, push-your-luck decision-making, and roguelike deckbuilding into an experience where every decision could be your last.
Success here means gambling your very life for cash (how 2026 corporate-chic) and maximising the synergies available to climb this terrifying corporate ladder. Just make sure to avoid JERRY cards. Everyone hates JERRY, and this is because he will literally murder you. Reveal cards to earn cash, learn clues to JERRY’s whereabouts on the board, LEAVE HIM WELL ALONE, and make sure you cash out before you crash out and face the corporate consequences…
