The story in the game is minimal and often communicated through logs and debug messages, providing a light but intriguing backdrop to the puzzle-solving experience. While some players appreciate the subtlety and integration of the narrative into gameplay, others find it lacking depth and engagement, with many noting that the focus remains primarily on the puzzles rather than a compelling storyline. Overall, the narrative elements serve to enhance the atmosphere and context of the game, but may not satisfy those seeking a more robust story.
- “The immersion of this game is surprisingly impressive, and the story (hidden in files as you uncorrupt the system, left over by your uncle) adds to all of that.”
- “There is a story to the game that I won't say too much about, but as you progress you get bits of information that you can piece together to learn what happened to the TIS-100 before you got to it.”
- “The story is interesting, and I do like the way it is integrated into the gameplay.”
- “The story is often overlooked.”
- “There are no levels, no story, no progression, no narrative, no music.”
- “My only gripe is that this story, despite all of its potential, simply does not provide enough depth to be satisfying.”

- “The game runs smooth, no crashes, and the graphics are just right to evoke the experience of using early GUI systems.”
- “TIS-100 lacks almost all hallmarks of a video game: no music, barely any sound, the graphics are intentionally '80s DOS' retro, the story is narrative visible, and typing keyboard commands is the main game control.”
- “No sound, no music, no graphics, hardly any story... this game is really about learning a simplified programming language and developing programs.”
- “If you need graphics/story this isn't gonna work out.”

The gameplay of TIS-100 revolves around programming tasks using a proprietary assembly language, offering a challenging yet rewarding experience for players, particularly those with prior coding knowledge. While the game features straightforward mechanics and open-ended puzzles, it requires players to engage with a retro PDF manual for understanding, which some find cumbersome. Overall, the game is praised for its depth and creativity, appealing primarily to fans of programming and puzzle-solving, though it may not be as accessible to those less familiar with coding concepts.
- “Overall, TIS-100 is an excellent game that deserves recognition for its creativity, gameplay, and educational value.”
- “Like in most Zachtronics games, the gameplay is very open-ended and there are multiple different ways to accomplish any given task.”
- “If you're into programming and this hits the sweet spot for you, you're probably looking at 8-40 hours of very fun gameplay.”
- “The gameplay style is so specialized that it's nearly impossible to grasp without reading the manual first.”
- “The only way to learn the mechanics of the puzzles is via the manual, which I like aesthetically, but really fails to teach the puzzle's practical mechanics and sets an expectation that there will be interesting lore and a storyline that is never delivered.”
- “Only two simple game mechanics are unlocked by completing puzzles, and they are both disappointing.”

The game's optimization aspect is highly praised, with players enjoying the challenge of refining their solutions for maximum efficiency and minimal resource usage. The limited assembly instruction set encourages deep engagement with optimization techniques, fostering a competitive environment through performance comparisons with friends and online leaderboards. While the focus on optimization can be daunting for casual gamers, it offers immense replay value and satisfaction for those who relish algorithmic challenges and coding puzzles.
- “One big part of the game's appeal is optimization - the art of not only getting stuff done, but getting it done as elegantly as possible.”
- “The game is perfect for those who love not just to solve coding puzzles but to optimize their solutions in order to gain maximum performance or minimal resource usage.”
- “Not only are some of the puzzles challenging enough on their own, trying to improve upon them for either code density or performance makes this game immensely enjoyable.”
- “The sense of accomplishment diminishes once you actually see how unoptimized your code was, shown the global statistics.”
- “10/10 would spend 20 min to find another solution only for it to be less optimized than the first.”
- “It's literally a performance optimization simulation.”

The game's music aspect is largely criticized for its complete absence, with many players noting the lack of any soundtrack or engaging sound effects, which detracts from the overall experience. While some appreciate the minimalist design for enhancing focus, others express a desire for at least some ambient music to enrich the gameplay. Overall, the consensus is that the game would benefit significantly from the inclusion of music, as it currently feels too sparse and lacking in auditory engagement.
- “Additionally, the game's minimalist design and immersive soundtrack create a delightful ambiance that keeps players hooked for hours.”
- “It's generally slightly changed but overall improved version of similar assembly-like programming puzzles; it has a better story, UI, has music, and is more enjoyable to play.”
- “A nice ambient soundtrack of some kind would be a welcome addition, but whatever, it's not exactly like there is a lack of music options that can be alt-tabbed to...”
- “There is no music, and the sound effects, too, are just digitized bleeps.”
- “Tis-100 lacks almost all hallmarks of a video game: no music, barely any sound, the graphics are intentionally '80s DOS' retro, the story is narrative visible, and typing keyboard commands is the main game control.”
- “No sound, no music, no graphics, hardly any story... this game is really about learning a simplified programming language and developing programs.”

The game offers significant replayability, particularly for players interested in optimizing their solutions and competing on leaderboards, as each puzzle can be approached in multiple ways. While many puzzles provide a satisfying challenge and metrics for improvement, some simpler puzzles may lack replay value. Overall, the combination of performance metrics and the potential for optimization keeps players engaged, though opinions vary on the enjoyment of this aspect.
- “Each puzzle gives a sense of satisfaction upon completion and has a great replay value where you can try different approaches to the same problem.”
- “As always, getting the solution is only the first step - optimizing provides huge amounts of replayability.”
- “The statistics you get after each completed puzzle, as well as the achievements, give a lot of replay value.”
- “Replay value: modestly low”
- “Although this concept itself doesn't bother me, the way the game is set up doesn't give me much replay value.”
- “It all boils down to a boring manual, little replay value (for myself), and little opportunity to create your own stuff with the code (as what you are given is very limited in scope).”
