The story in Spacechem is presented primarily through text passages between levels, which some players find engaging while others consider it minimal and easy to overlook. While the narrative adds context to the gameplay, it is often deemed secondary to the puzzle-solving mechanics, with many players opting to focus on the challenges rather than the storyline. Overall, the story is described as intriguing and well-written, but its delivery may not resonate with everyone, making it optional for those more interested in the puzzles.
“The story is intriguing and is interesting and is displayed through text only.”
“Spacechem offers dozens of puzzles in a story-driven campaign, where you need to design and optimize atomic assembly lines.”
“The way Spacechem wraps it into a Lovecraftian space adventure provides an interesting story, if sometimes a bit predictable.”
“The only thing I didn't like is that the story isn't very connected to the puzzles except for defense assignments and the last two planets.”
“The story is given as text for the player to read in their spare time, which is one of the worst ways to tell a story in games, in my opinion.”
“The story is hard to digest because it is only available in text form and progresses very slowly as you take more and more time to solve the increasingly difficult puzzles.”

The gameplay is highly praised for its depth and complexity, offering a rewarding experience through challenging puzzles that require strategic thinking and optimization. While the mechanics are initially simple, they evolve throughout the game, introducing new elements that keep players engaged, though some users noted that the tutorials could be clearer. Overall, the game is considered a standout in the puzzle genre, appealing particularly to those who enjoy mechanical and programming-like challenges.
“It's a great puzzle game and has very interesting and fresh mechanics that keep me coming back.”
“The gameplay consists of putting commands on a line where a 'waldo' travels.”
“The simple mechanics which lure you in are expanded in consistent and interesting ways to create a wonderfully complicated yet approachable puzzle machine that will leave you tinkering for hours, trying to optimize your fabricators.”
“On top of that, some of the game's features are not explained very well, though online guides do help break down the mechanics.”
“The main problem with this game is that there isn't enough in-game help to understand the mechanics.”
“The actual gameplay was a bit bland.”

The music in the game receives mixed reviews, with some players praising it as fantastic, charming, and fitting for the gameplay, while others find it repetitive or odd, leading them to turn it off. Despite the varied opinions, many agree that the soundtrack enhances the overall atmosphere and complements the challenging puzzles, making it a notable aspect of the game. Overall, while some players appreciate the music's originality and motivational qualities, others feel it lacks variety and can become tiresome over extended play sessions.
“The music is charming and a joy to listen to, with some great ambiance and background noise to get the mind working.”
“The soundtrack is amazing.”
“The music sets the tone of curious excitement, with the puzzles getting more and more challenging and rewarding.”
“The choice of music is questionable, so I turned off the music volume, but the gameplay itself is 10/10.”
“I just turn off the music because it's weird.”
“The music is... I honestly have no clue, there's too little of it for how long the game runs on and I had to turn it off and put on my own music after a while.”

The graphics in the game are generally described as outdated and simplistic, with many reviewers noting that while they are not visually impressive, they are functional and do not detract from the gameplay experience. Some players appreciate the minimalist design, which allows for a focus on puzzle-solving, while others express frustration over the lack of display options and resolution issues. Overall, the visuals are considered adequate for the game's mechanics, though an update would be welcomed by some.
“Even if the graphics are a little dated, they are highly recommended for anyone looking for a mental challenge, and hours upon hours spent on making stuff work.”
“The graphics are very basic, but that doesn't take away from the complexity of the puzzles.”
“The austere environment of reactor grids is accompanied by beautiful hand-drawn visuals of various planets and cosmic monsters.”
“I bought this thing with outdated graphics at a 75% discount, for reasons unknown to me.”
“It seems like a great game, but I'm unable to play it due to its graphical/lack of display settings, and just scrolling through the forums and discussions, it seems like I'm not the only one with the problem.”
“Could use an update on the graphics (no widescreen support).”

The game's optimization aspect is both a core mechanic and a source of frustration, as players engage in complex puzzles that require creative problem-solving and programming-style solutions. While the game is well-optimized in terms of performance, the learning curve can be steep, with inadequate tutorials for advanced optimization techniques. However, the satisfaction derived from achieving highly optimized solutions and competing on leaderboards adds significant replay value and appeal for those who enjoy mental challenges.
“Great optimization game.”
“Excellent puzzle and optimization game.”
“The bulk of the replay value for this game comes from the researchnet puzzles; which are way harder than the campaign puzzles and may require some unconventional techniques to solve, and secondly from optimization of previously completed puzzles for time, number of symbols or reactors used.”
“The tutorials are pretty horrible at explaining a few optimization tricks that are required to get the best possible solution.”
“Spacechem is a great game if you're not serious about it, but if you like mathematics and optimization, you will get frustrated really fast.”
“It's like programming, with all the same issues: ordering problems, poor optimizations, bottlenecks, asynchronous operations, thread collisions, waiting on I/O, interrupt-driven handlers, buffers, and so on.”

Overall, the multitude of solutions and the focus on efficiency provide a compelling reason to revisit the puzzles.
“Spacechem has, for all practical purposes, endless replay value.”
“In addition, once you've made it through the game, the researchnet allows you to access user-made puzzles, of which there is a very large number, giving plenty of replay value.”
“You build molecule factories in an almost-sandbox environment, with gradually ramping up complexity - all the puzzles have many solutions, and there's great replay value in optimizing your designs.”
“There is access to user-created content, but the replay value is somewhat limited once you master the game.”
“One issue with that replayability is that there isn't an obvious way to back up your previous solutions, which made me reluctant to wipe the slate clean on my nicer solutions.”
“Hard to find something bad to say about this game apart from it not having much replayability apart from making your designs more efficient.”
