The Long Gate

TL;DR:
Buy this game if you want to solve challenging and logical puzzles! You'll need some patience to learn what it wants to teach you, but it's worth it!
Full review:
The Long Gate is an enjoyable and minimalist puzzle game.
It's a game where every time I walk into a new area I'm like "oh fuck off" because the problems seem too difficult at first glance. At the same time, I've yet to come across a puzzle that hasn't made sense, or that I couldn't solve, or that I didn't enjoy solving. I say this in the best way possible.
There's a great satisfaction in solving the Long Gate's puzzles because the solutions often aren't immediately apparent, but they truly do make sense. When you work out the correct solution or sequence of actions, there's a strong sense of reward for the patience you showed while trying to make sense of the unfamiliar.
I've not yet finished the game, but have really enjoyed it so far. It's been quite stress relieving and I find myself coming back to it quite easily.
I did a year of programming back at the start of uni a few years back, so I was familiar with some of the concepts the game introduces early on.
I've also dabbled with redstone projects in Minecraft and the puzzles you solve with circuitry in The Long Gate are sort of similar.
If you don't want to learn binary, or bit flipping or how circuits work, then this isn't the game for you.
If you can't accept that this game was made by a very small team and isn't perfect, then this game isn't for you.
Otherwise, the puzzles definitely are challenging, but I do think that keen newcomers unafraid of a challenge could give this a go and enjoy themselves.
I've found the game runs alright too on a gtx 1070 and ryzen 3600, though I do wish there was a cleaner AA implementation. The highest setting obscures texture detail in the distance, but turning this down introduces aliasing.
With that said, it's still a good looking game with a clear atmosphere that is well supported by a low-key soundtrack. The sound effects are very mechanical too, which really adds to the cyber-industrial aesthetic of the game.
I think this game is very underrated and definitely recommend giving it a go.
I bought it at full price and am very happy with my purchase :).

A logic game that covers a wide range of circuits and electronics topics.
It's a good learning experience, and makes it really interesting to play with concepts that are normally kinda bland.
I would recommend this if you really like logical puzzles, want to play with computing in an alternate way, or want to get more of an understanding how electronics work.
I would probably not recommend this if you are looking for easy puzzles, or are looking for a story game. This game's about the puzzles, and expect them to take some effort.

Just finished the game. Excellent!
I was blocking at one segment and by chance I realized that there was a specific thing to do before searching for help on the internet.
Nice quantum level. I did not understand everything, and far from me to understand how a quantum computer works. I just made the inputs mostly by intuition, which was apparently sufficient.
I wish i could have had this game when learning about boolean algebra, pass-by filters, binary conversion, RLC circuits or Q-bits at early years of university.

Surprisingly polished: awesome world design, fair puzzles, great difficulty progression. I enjoyed this. It gave my brain a good workout.
Compared to other games, I'd say this is a bit expensive, but on a 50%-off sale it'd be well worth it.
On to the bad side: though the puzzles are polished, there are a lot of technical annoyances: as soon as you start interacting with puzzles your mouse sensitivity drops massively. It feels awful. Some puzzles had me picking up my mouse to move back to the other side of the mouse pad several times just to drag something half-way across the screen. Also, performance is bad: In some areas even a 3090 TI will fall below 50 FPS when shadows are set to High. Switch to Medium and suddenly it's smooth 120+FPS. The game physics seems to have a different frame-rate. Sometimes the graphics were at 120FPS but half the things on screen were juddering as if it were sub-30FPS. Sometimes I would enter the right input for a puzzle and it wouldn't be recognized because something was invisibly slightly out of place.
Also, if you know anything about electronics or quantum computing, you'll find it a lot easier as the puzzles mostly resemble textbook exercises from those fields. I still enjoyed the brain workout despite it not introducing any new concepts to me though.

A well made if rather hard puzzle game that's very heavily in computer science and engineering topics takes about 8-9 hours to finish

A hard puzzle game, which feels a great sense of accomplishment after solving those puzzles. Hope for more contents later.

It's a puzzle game based on computer science concepts. I consider it more challenging than the average based on other puzzle games I have played. If you like puzzle games there is no reason not to try this one out.
