- “The story is simple yet intriguing, and I feel a lot of urgency to help the world.”
- “The missions are fun to do, with some being really challenging in a fun way.”
- “The story mode is nice, but the sandbox is where Aviassembly really shines.”
- “The story is very basic, and the structure -- unlock parts, upgrades, and missions as you progress towards a final mission -- but how you achieve that is basically unconstrained creativity and practicality.”
- “The missions can get a bit repetitive, and the story from what I've seen so far is nothing to write home about.”
- “The story mode is relatively short - I was able to work through it in about 7 hours.”

The gameplay of this title is characterized by a simple yet engaging loop that involves building aircraft, completing delivery missions, and upgrading components, reminiscent of games like Kerbal Space Program. Players appreciate the intuitive building mechanics and the balance between challenge and relaxation, although some note that the missions can become repetitive and the overall content is currently limited, with around 6-10 hours of gameplay available. While the flight mechanics are arcade-like and not highly realistic, they are generally enjoyable and accessible, making the game appealing to both casual players and those interested in aviation.
- “The gameplay loop is nice, going flying from airport to airport fetching cargo for quests.”
- “The core gameplay loop is engaging and unique enough to hook you.”
- “The mechanics of building are detailed enough to be really creative, while simple enough not to be tedious or too fiddly.”
- “The gameplay is pretty dull fetch quest type stuff, and the quest balancing vs actually being able to make for a more interesting game seems off.”
- “The flight mechanics need a lot of work (planes shouldn't lose all their speed and plummet like a rock the moment the engine is turned off, why is gliding basically impossible?) and a lot of the fetch quests are just unnecessarily frustrating.”
- “The gameplay does get a bit repetitive after the first island, but maybe that's just me.”

The music in the game is generally described as relaxing and fitting, enhancing the overall experience with a chill vibe. However, many players express a desire for more variety, as the in-flight tracks can become repetitive over time. While some appreciate the aesthetic quality of the soundtrack, others find certain pieces overly familiar or even distracting, suggesting a need for additional tracks to maintain engagement.

- “The music is very, very repetitive while flying... I hope there will be some variation.”
- “The in-flight music is a stock track that was incredibly common online for over a decade.”
- “All that said, the music while flying got really repetitive; that is my only gripe after hearing that song for 12 hours.”

Overall, players find the grinding aspect of the game to be a mixed experience. While some enjoy the repetitive nature of missions and the gradual progression it offers, many feel that the early game can be particularly tedious and grindy, leading to moments of frustration. However, the creative building mechanics and fun gameplay loop help to balance out the grind for many players, making it an enjoyable experience despite its flaws.
- “I actually get to build my aircraft ideas that I thought of in the past (as far back as when I was halfway through my aerospace engineering studies) and get straight to flying it, no tedious or complex tinkering (such as checking pressure, buttons, safety checks, etc.), just straight to the fun of flying your creation, which I preferred the most.”
- “You'll need a second life for grinding.”
- “The progression is tedious at times, but overall still rewarding.”
- “Although completing the story mode with the realistic-looking airplanes from the trailer is tedious, the game enables you to create and apply a design of your own, however strange.”
humor

The humor in the game is a standout feature, with players enjoying the absurdity of creating and flying hilariously impractical planes, often leading to comical crashes and unexpected outcomes. The intuitive gameplay allows for creative freedom, making it accessible and entertaining for all ages, while the developers' lighthearted approach adds to the overall fun. Many players find themselves laughing at the ridiculousness of their designs and the game's physics, making it a delightful experience filled with silly moments.
- “The thrill of seeing your hand-crafted plane actually fly, or even hilariously fail, is where the game’s magic lives.”
- “Amazing game, lets you get very creative with your builds and create funny monstrosities that should not be able to fly - and yet they somehow do, like a gigantic bumblebee.”
- “It's easy to sink hours into experimenting, tweaking, and inevitably watching your beautifully ridiculous inventions wobble hilariously through the sky.”

Overall, the game's optimization is a mixed bag; while many players appreciate the smooth performance across platforms and the engaging design mechanics that encourage tinkering, some report significant performance issues, including frame rate drops and bugs. The game effectively balances various design variables, but players desire more detailed metrics to assess optimization effectiveness and express concerns about the accuracy of displayed part stats. As it is still in early access, there is hope for future improvements in optimization and performance stability.
- “The challenge of managing all the different variables (drag, weight, cargo, etc.) was the best part for me trying to make the most optimized plane for the task.”
- “Performance is smooth across platforms, including the Steam Deck, which makes it ideal for quick pick-up-and-play sessions or extended design marathons.”
- “A fun little game with a perfectly balanced editor between many possibilities and ease of use and optimization.”
- “It would be nice if there were more numbers involved to make it easier to figure out if optimizations are effective.”
- “However, the performance isn't amazing; it’s not unplayable, but I was a fair bit above the minimum specs and I was struggling to get a consistent 60fps even with SSAO disabled.”
- “The game cuts a lot of physics corners to make the game cheap and acceptable performance-wise, but this makes the game not as long-lasting as it should due to this simplicity.”

The game's replayability is a mixed bag, with some players praising its fun mechanics and infinite replay potential, while others criticize its limited content and lack of a new game+ mode. Many feel that the game is enjoyable but short, leading to a decline in replay value after initial playthroughs. Overall, while there are elements that encourage replayability, such as sandbox modes and customization, the absence of additional missions or content updates leaves some players wanting more.
- “This game has a lot of replayability and a lot of fun mechanics to play around in.”
- “The progression is immensely satisfying, and there is a good amount of replayability for those willing to either replicate a plane from the real world or try something crazy.”
- “I would still recommend it because the campaign and the sandbox mode have a lot of replayability.”
- “Replayable, but replay value is limited in that there's no new game+ mode or anything - once you finish, that's it.”
- “Got me hooked for the first 7 hours, but it kinda became boring after that; it lacks replayability other than sandbox mode.”
- “Great small game, very simple and straightforward, but there is no replayability and after 10-15 hours of gameplay, it's over.”

- “Really loved the atmosphere and pace.”
- “Charming, atmospheric, relaxing, intuitive, elegant and very fun!”
- “This game has a charming atmosphere and compelling gameplay.”
