MainFrames invites you to meet Floppy and to browse a clever and charming platformer that plays out entirely within the windows and desktop of a PC monitor. You won’t want to press the escape key on this cozy outing!
Questions
Is it really free?
Yes. MainFrames Demo is free right now on Steam, with nothing to pay.
Is this the full game?
No. A demo is a portion of MainFrames Demo — usually the opening section — published so you can try it. It is free permanently, but it is not the complete game.
Where do I claim it?
On the official Steam page. We link straight there — we never host game files or act as a middleman.
