Aviassembly is an indie flight simulation game that entered Early Access on April 11, 2025 . Developed and published by Jelle Booij, the game offers players the opportunity to build and fly their own airplanes, complete missions, earn money, and discover new locations in an open world.

Build, Fly, and Explore
In Aviassembly, players start by constructing their first aircraft from basic components, such as a broken bicycle, duct tape, and an old engine. As missions are completed, players earn points to unlock more advanced technology and money to purchase better parts, allowing for the creation of larger and more efficient planes.
Gameplay Mechanics and Challenges
The game features a simplified aerodynamic model, where each wing part has fixed lift and drag values. This allows players to deduce the lift-to-drag ratio for each choice, although the system lacks detailed aerodynamic parameters like Cl or Cd.
One notable aspect is the engine control, which currently has three states: full power, off, and full reverse. This design choice requires players to apply “blips” of power and glide the rest of the way, which can be challenging for those accustomed to traditional flight simulators.

Community Feedback and Developer Engagement
Players have provided valuable feedback through the Steam Community forums. Suggestions include adding more detailed instructions for the building section, implementing air brakes for better landing control, and indicating runway directions on the map to assist with navigation.
The developer, Jelle Booij, is actively engaging with the community, considering feedback for future updates. This collaborative approach is a hallmark of successful Early Access titles, allowing for iterative development based on player experiences.
The Road Ahead
While Aviassembly is still in development, its unique blend of aircraft construction and mission-based gameplay offers a promising experience for flight simulation enthusiasts. As the game evolves, players can look forward to more refined mechanics, expanded content, and continued community-driven improvements.
