Never got hit by bugs in Machine for Pigs, luckily. The AI wasn't much good though. One time I was stood on some bucket & a Pig wouldn't attack, just stood about, until I turned & then it attacked.
As for the game itself, it is okay, but absolutely not worthy of the Amnesia title.
The perma light, the doors/drawers/objects that couldn't be interacted with at all. The lack of spookiness compared to A:TDD. That blue fog. I mean, come on, wth were they thinking!? (luckily could be turned off via .Ini's.
I've played A:TDD countless times & will some more.
SOMA is another great.
Basically, anything made by Frictional Games is a certain hit :D
