Our take on IFO

The bounce point arrives when the game leaves players to infer both controls and objectives from an alien presentation. Anyone expecting a readable tutorial or familiar spaceship interface will meet the central obstacle immediately: progress depends on testing systems and interpreting their responses.

What is IFO?

IFO presents an alien spaceship as a puzzle built around simulation and rule discovery.

Players inspect the craft's controls, experiment with its systems, and observe how different sections behave. By forming hypotheses from these observations, they work out each section's rules and objectives before completing the assigned mission. The game keeps its original alien language and presentation rather than translating or redesigning the interface. IFO is part of CosmOS 9, a collection of 9 puzzle games found on a mysterious console drifting through outer space.

How IFO plays

01Alien Control Systems: Players interact with spacecraft functions presented in an unchanged alien language and visual style.
02Rule Discovery: Each section requires observation and experimentation to reveal how it works and what it requires.
03Mission Completion: Progress depends on applying the discovered rules to finish the assigned spacecraft objectives.
