The gameplay of this educational game is criticized for lacking engaging elements, with users noting a lack of tasks, accomplishments, and interactive mechanics, which can lead to boredom, especially for those unfamiliar with Arduino Nano. While the visual representation and interface are praised for their clarity and alignment with CAD systems, the absence of physics components and workshop support limits its educational utility and overall gameplay experience.
- “Great work on the visual representation and view control (which matches most CAD systems for all you mechanical design folks out there), and I find the interface to be clean and simple.”
- “The wiring mechanic is awesome - super flexible.”
- “This educational game is a good experience for gameplay, serving as a replacement for traditional educational software.”
- “There are zero gameplay elements.”
- “It certainly hasn't got anything for you to really complete, no tasks (not even for learning) nor accomplishments (even in the most sandbox of sim games you still have gameplay loops, something that is simply not in the scope of crumb).”
- “There's nothing for 'physics' (motors, steppers, effectors or visual 'mechanical' outputs) or basic sensors (IR, microphone, etc.).”

The game's stability is heavily criticized, with users reporting numerous bugs, instability, and an overall sense of incompleteness. Many feel that the developer has abandoned the current version in favor of a sequel, leading to frustration over what they perceive as a poorly executed demo. Key functionalities, such as part placement and tool switching, are described as problematic and hinder the overall experience.
- “It's buggy, unstable, and incomplete.”
- “Developer seems to have abandoned this in favor of working on a sequel - which I'm keen to see when it comes out but can't help feeling like I've paid for a buggy demo so the dev can go off and make the full version.”
- “As a programmer myself, I would be ashamed to release something this buggy.”

The optimization of the application shows promise with great models and lighting, but users report significant performance issues, particularly with analog circuits, leading to high CPU consumption. While some improvements have been noted since the introduction of updates, crashes during experimental features like Arduino code compilation remain a concern. Overall, while the potential for future enhancements exists, current performance is not robust or real-time.
- “Edit: since using crumb, the amount of consistent fixes for performance and additions is great.”
- “The models and lighting are great; performance was great, but sometimes it would crash after compiling Arduino code, but that can be expected while it is an experimental feature.”
- “But it's also the most CPU-consuming simulator I've ever used; anyway, it's recently published, so developers may improve the performance for this app in the future.”
- “However, the rotary switch on the power source is hard to modify, and it costs high performance of the GPU.”
- “This is okay for TTL and basic oscillators, but any kind of analogue circuit is terrible for performance; I wouldn't call it powerful or real-time.”
- “But it's also the most CPU-consuming simulator I've ever used. Anyway, it's recently published, so developers may improve the performance for this app in the future.”
graphics

The graphics in the game are generally praised for their nice 3D perspective and overall quality, contributing to a unique experience, particularly in the context of revisiting an electronics lab. While some users note that the visuals may appear somewhat incomplete, they agree that the graphics do not significantly detract from the overall gameplay experience, with ratings around 7.5/10 reflecting a solid appreciation for the visual design.
- “The 3D perspective and nice graphics make it a unique experience of digitally revisiting the electronics lab.”
- “I will say that the game is done well, the graphics are good, and the functions are logical.”
- “The positive, however, is that the graphics are nice (if they seem somewhat incomplete), and none of the issues I've mentioned are serious enough to detract from the experience.”
grinding
8 mentions Positive Neutral Negative

Players find the grinding aspect of the simulator to be tedious due to a lack of quality of life features, numerous bugs, and cumbersome controls, which can lead to frustrating misclicks and slow progress when building large circuits.
- “The simulator is lacking a lot of quality of life features, making it really tedious to build large circuits.”
- “There's a lot of bugs, and the controls are a little tedious.”
- “If you're a misclicker like me, you'll find this very annoying and tedious.”

The story aspect of the game is met with mixed feelings, as players express excitement over building components like the jam-1 CPU but are frustrated by missing critical parts and cumbersome tooltips that hinder the experience. The narrative elements, while present, are often overshadowed by gameplay mechanics that complicate the storytelling process.
- “Placing the breadboard was a mission of its own, but I figured it out, and then you can add power strips to the side of the breadboard. Cool!”
- “Many tooltips cannot be resized, which is very annoying when there's a legitimate short story of a manual for operating a part inside that panel.”
- “Many tooltips cannot be resized, which is very annoying when there's a legitimate short story in the manual for operating a part inside that panel.”
- “I was excited to go build the JAM-1 CPU from James Sharman, only to realize that mission-critical ICs are missing!”
- “Placing the breadboard was a mission of its own, but I figured it out. Then you can add power strips to the side of the breadboard, which is cool.”
