DEAD SPACE

So last week, I picked up a copy Dead Space at a bargain bin for $3.
For those who never played the game, it is basically Resident Evil 4 in SPACE.

Anyway, popped the game into my PS3 and for shits and giggles started my first playthrough of the game on the hardest difficulty setting available. Now the whole thing feels like an abusive relationship to me, mainly because I just can't stand jump scares and this game has TONS of 'em - I can never play for more than an hour and somehow I keep finding myself wanting to go back, craving for more. But as soon I loaded my save file and made some good progress and can't stop thinking stuff like "Why do I keep doing this to myself? Now I can't turn off the game, because if I turn of the game now I'm gonna lose all my progress.".

I wonder if it is because Dead Space is actually a well-designed game or I'm just starting to lose my mind?

I'm now on Chapter 10.
