Our take on MainFrames

The desktop is not just a backdrop: rearranging program windows creates the paths Floppy uses to move between frames.

What is MainFrames?

MainFrames is a platformer set within a PC desktop, where Floppy, an adventurous program, travels through a digital world.

Move between program windows and rearrange them to create paths, then jump across frames to explore maze-like areas. Along the way, meet colorful characters and discover secrets connected to Floppy’s search for their purpose. The game combines platforming challenges with puzzles, area-specific visual styles, and a soundtrack described as micro-chill. Cheeky daemons are part of the setting, keeping the system balanced while staying out of sight. The journey uses desktop windows as both its environment and a way to navigate.
