Yet another asset flip, costing money, that should be removed from the Steam Store. You an easily tell by the nonexistent plot, nonexistent instructions nor tutorials, minimal graphic animations and repeated layouts that are re-used and repeated throughout the map. Grandpa fails as a horror survivor game not only because of the reasons above, but the controls are also just as bad. The camera sensitivity is horrid, even at the default 50%. A small turn and my entire screen is spinning towards the Twilight zone, which makes it even worse to move around let alone navigate with the crappy sensitivity. There's no explanation on the dude who's always chasing you around the map, from the moment you spawn. The entire game-play was just me figuring out what to do, until I found a utube guide.
I would advise to avoid playing Grandpa, unless you want to spend 30 minutes of confusion and frustration as I have ... Heck, I wouldn't play this game even if it was free.

Not a bad game, its very hard like...way harder than granny, and its supprisingly not buggy, id give it 4 stars.
