Proxxy

Proxxy is a cooperative platformer for one to four players in which a team escapes a linear level filled with unpredictable traps. The players wear explosive collars that detonate if they move too far apart, and the death of a single player restarts the run for the entire team. Two modes are available: Realism, which restarts the full level after each death, and Easy,
which resumes from the last checkpoint. The game is hosted by an in-game gamemaster named Proxxy.
