Insight

tl;dr: Play Understand first.

Insight is not entirely different from Understand — both share a minimalist style and a naming convention of choosing un-googleable titles. Compared to Understand, Insight leans heavier into testing your spatial reasoning. Insight is not executed as well: it's more difficult to experiment in Insight, since the game often fails to indicate whether you've broken a certain rule or not — unless your solution happens to satisfy a different rule first.

Insight doesn’t always test your understanding effectively. I sometimes reached the final level of a set with only a vague guess about how some of the rules were meant to work, even though I hadn't resorted to bruteforcing any of the solutions. It’s disheartening to find out that my assumptions were wrong all along after I've spent quite a while chasing a solution I thought should have totally worked. Sometimes solutions don’t count for reasons that feel arbitrary — like when your line turns at an already existing corner. If that’s never allowed, it shouldn't be possible to do so in the first place.

Nevertheless, the parts that do make sense are still very enjoyable (and there are plenty of them!). Given the low price and the generous number of levels, I still recommend the game — but only if you’ve already played and thoroughly enjoyed Understand.

The puzzle design in this game is really excellent. Most of the puzzles have relatively few solutions (not always unique) and they can often be logically deduced.

On the flip side, I wish there was an explanations system for the game - maybe as you complete a set of levels there could be a dictionary of rules revealed. Since some of the rules are a bit obscure, and the game introduces many symbols, it can be hard to keep track of them between sessions even if you figure out what they mean.

This Witness-like gets pretty hardcore fast! The UI is modest, there’s no music but simple sounds, but don’t get fooled by the looks.
