About .T.E.S.T: Expected Behaviour — Sci-Fi 3D Puzzle Quest

.T.E.S.T: Expected Behavior is a 3D first-person brain twister in a sci-fi setting. Solve puzzles to test your logic, think outside the box, act fast and use your skills to adapt to unfamiliar situations.

.T.E.S.T is full of both new and classic mechanics, but they are so deep that some still aren't fully revealed. The game will make this clear to you. Again and again you'll see that each rule always has some additional nuance. This can keep going forever. Keys, doors, moving platforms, even jumping will open up from a whole new angle.

You'll be faced with:
– 119 levels
– Time manipulations
– Curved space
– Player-controlled level structure changes
– Transfer of consciousness to another body
– Multiple game zones with unique mechanics
– Classic mechanics in a new form
– Non-linear level map
– Some puzzles are about exploring the game's rules
– Logical puzzles

Plus, for what it's worth, the fate of the human race is at stake. What exactly is happening to it – that's just another riddle waiting to be unraveled. You'll have to collect the facts one by one if you want to discover the truth.

This is an awesome puzzle game. It is easily one of the better first person puzzle games out there. This game has tons of levels and the difficulty of these levels ranges from easy to brutally hard. Some of the levels took me more than an hour to complete. A few took me around two hours to complete. You have to endure this difficulty and be patient to be able to finish this game. There are a few levels in this game which you will probably hate because they require very tedious actions or high precision. It is a good thing there is a rewind button because you will be using it a lot. Most of the levels are fun to solve. The levels are diverse and very creative. There is a story in the game but it is very thin. Only the intro and the end movie told the story. I succeeded in finishing all the levels except one very small level called ‘up’. Luckily that level was not mandatory to finish the game. I had great fun playing this game and finishing all the levels. I highly recommend this game to serious puzzle lovers.

This is a very cool puzzle game with loads of cool mechanics. However, having tons of different puzzle mechanics leads to situations where some of them are not very good. For example, almost half the "Lifts" levels are dreadful and I don't think they can be solved without drawing some sort of diagram on a piece of paper simply due to the amount of moving parts involved. Throw in the fact that some of those levels rely on you using lifts in unconvential manner and it becomes a nightmare. I looked up like 5 of those levels because they are just miserable to do on your own. The rest of the levels are very cool though and throw very interesting concepts and problems at you, I had a lot of fun solving them. There are a couple of levels that require you to have somewhat fast reflexes, but there is a tool in the game that makes it much easier. Oh yeah, and there is also the unfortunate situation with the achievements - there is a set of 10 achievements that require you to complete levels without using some of their mechanics, which sounds fine on paper, but the way they were implemented was half-baked: the devs just set a 0/1000 level counter for each, and you can't reach that because r…

Not recommended Jul 3, 2024
I don't often give negative reviews for games, mostly because there is an important distinction between "I don't like this game" and "this game is bad". I won't say this game is [i]bad[/i], but it's definitely [b]not[/b] what it claims to be, which is a puzzle game. The game starts off with an intro sequence of a man (you) being abducted by aliens. You can overhear (and for no explainable reason, understand) two (presumable) aliens talking about you; the gist of it seems to be that this is supposed to be some sort of test to prove that humans are intelligent. (Never mind the fact that the abductee was driving a motor vehicle on a paved road, which would be an impressive feat if our species lacked the problem-solving abilities they seem to be testing for.) None of the rules of the puzzles are explained explicitly, except through hints that can be gleaned from the aforementioned overheard conversations between the two aliens. I don't see this as a problem -- in fact, it can be a hallmark of an excellent puzzle game; consider Myst, The Witness, and The Talos Principle -- all three dump you into their respective worlds without any explanation of what to do next, and it's on you t…
