Fly Over! 100km! Mountains! Will Turn Paid on November 16
A free Steam release converting to paid while honoring existing library owners is a monetization step tied to ongoing development costs, not a delisting.
Reporting from 1 source: Automaton.
The PC Steam endless flight game Fly Over! 100km! Mountains! will become a paid title on November 16, the developer announced on October 9. Players who add it to their library before then keep free access to future content. Its Steam user reviews sit at Very Positive, with 81% of 59 reviews positive, and the developer cites development and maintenance costs plus continued updates as the reason.
The game launched for free on Steam in October 2025 as a rear-scrolling endless flight title: the plane flies itself, the player dodges obstacles with WASD or a stick, and a tornado closing from behind forces timed use of a fuel-limited boost. Development and maintenance costs, along with continued updates, are the stated reasons for the switch. Anyone who adds it to their library before November 16 keeps free access, including future content, and the paid DLC for achievements and aircraft is unaffected. The post-switch price has not been announced.
