Meh, get it on sale.
It has some great puzzles and some really awful puzzles, pretty nice graphics and consistent theming throughout, the walking speed is painfully slow but there's a run button (c by default for some reason), and the story was bad but barely relevant, though it unfortunately drags down the last 5 minutes or so of the game with a weird ending that railroads you through unfailable "puzzles" for dramatic effect

Puzzle highlights:
-figure out and continue patterns
-combine basic math problems with clues to find code
-find environmental clues

puzzle lowlights:
-count objects
-keep track of several complex clues/instructions at once, exiting the puzzle and navigating a menu every time you want to reread them
-the same "flip all the levers on but they effect other levers" puzzle 3 (4?) times
-connect the pipes but some of them turn surrounding pipes
-basic algebra level math problem ((x+y)/z = 7, where y is given and x and z have preset possible numbers)

Fun escape room! Only complaint is the walking speed is weird. When you press W it takes you a second to accelerate into a walk. This drove me crazy. Overall I enjoyed myself and will buy more escape room games from this developer.

I purchased this game in the mc2games escape room bundle (on sale), and found the difficulty of the game 'just right'. I did look up the meanings of some symbols around mid to late game, but it was just to recall what the symbols meant. Turns out it had nothing to do with the puzzle at all and I was overthinking it. I overthought a couple puzzles which probably extended my playtime by about an hour or so. I played it in one sitting and achieved just under 4 hours of playtime.

I felt the puzzles were fairly well designed, though I did find one puzzle whose solution made some sense, but I still didn't quite understand the logic behind how to solve it (I may have somehow managed to brute force it while applying what I felt was correct logic). I should've studied the solved puzzle a bit more to see if I was on the right track (probably was). That is a 'me' issue and not a knock against the game at all.

I found myself having a-ha moments several times and grinning while complementing the puzzle out loud to myself.

The environment is well designed, I encountered no glitches, issues, or crashes.

There isn't much story, but it is enough to keep you engaged. Walking speed is indeed slow (you'll see that in other reviews) but each room is self-contained, you won't be doing much walking or backtracking.

My general go-to criteria for game value is 1 hour per $1 spent. This game comes close, and I felt I got my full value out of it (taking the value of the bundle, divided by the (5) games).

I already look forward to installing their next game. I'm playing them in release order.

I would definitely recommend purchasing the game on sale or with the escape room bundle.
