- “If you're looking to really test your noodle this may feel a bit shallow especially with the lack of variety in mechanics.”

The game's optimization aspect is a mixed bag, offering satisfying challenges for players who enjoy fine-tuning their solutions, though some reviewers noted a lack of creativity and a tendency for obvious "best" solutions that can limit further experimentation. While the puzzles are generally easier, they allow for a greater focus on optimization, with various axes to explore, making it appealing for dedicated fans of the genre. However, casual players may find the optimization depth insufficient to maintain engagement throughout the game.
- “It is very satisfying to watch your machine working, and disappointing to discover that your fancy contraption is on the right end of the performance histograms.”
- “Tight, satisfying puzzles with a great pull for continued tweaking and optimization.”
- “Different axes of optimization (time/area/cost) are fun to explore.”
- “There's practically no need for creativity, and there's often an obvious 'best' solution that disincentivizes further tinkering/optimization.”
- “No limit to solution size means that you can easily just cruise through the game without having to optimize, but the space for optimization is definitely there.”
- “Maybe for a more casual player there are not enough medium-difficulty optimizations to stay engaged, but if you go looking for it the depth absolutely is there.”
