Haha, not when I close my eyes, but when I sleep. Back when I played this I would be up till 5am because I enjoyed its story, and when I slept I would be playing the game in my mind still. I would just throw a bunch of blocks in place and start going through all the possible ways to climb them then throw more on and do it again. It was maddening, felt like I spent 6 hours of my sleep every night playing it. It was very nightmare like, which is very fitting considering the game that caused it.
But I look back at it with fondness, my only fear of trying to 100% this game is that my mind will obsess over it again and I will start playing in my dreams again.
