In terms of theme and environment, the game is amazing! Very simple yet it hits close to home. In terms of mechanics, it gets borderline unplayable at times. Specifically, the mouse sensitivity. I can't even get past the ending it's so difficult to deal with. It massively detracts from the experience, at least for me.
Edit: I was writing this in the middle of playing the game, the sensitivity fixed itself once I clicked back in. I guess it was just a bug. It still kinda sucks, but it's playable.
Edit 2 (within the span of a minute): Forget it, it breaks OFTEN. I hope you can fix this but until then it's a no for me.
