I didn't dislike it in itself, but I thought it compared pretty unfavorably to its obvious sources of inspiration: LIMBO and INSIDE.
I found the controls fiddly, and the gameplay did annoying things like the character not automatically grabbing an edge when you jump, or the absence of "contextual behavior" (you have to press a different button to crawl or to sprint in addition to the movement key; in INSIDE the character automatically adapts his pace/stance to the situation). This artificially increased the difficulty for me.
There was not much variety nor cleverness in the "puzzles" you had to solve, you're mostly just running away from enemies and jumping or climbing on things (there's a lot of that in INSIDE too, but there's a lot of other things as well, that's not the whole game).
I did like the environments and the atmosphere, though there were a lot of clichés too, and after finishing the game I realised that the whole thing was basically a revamp of Spirited Away with a horror twist on it.
Now all this I could have looked over more easily if the retail price hadn't been twice that of LIMBO. I expected to play a big-budget, big-production LIMBO, and that's far from what I got.
It was quite short too but here LIMBO and INSIDE are guilty of the same sin so I won't hold that against it.
Overall I don't regret playing it and finishing but I won't go back to it again (whereas I replayed LIMBO and INSIDE to completion multiple times already).
