What I meant was an instant way to just replay any level that you want to play so that you can get your high scores and stuff. I meant like, a list of levels that you've played and it's like "Hey, check it out, you got 322,199 points on this level, and haven't earned the gold medal yet." in the form of a level name, number for score, and a faded little gold icon, you know? That kind of level select. The fast travel system sounds like it's ideal in that sense.
ooh, a horror game? I'm too scared of horror games. I saw Amnesia on sale so often, I go to the store page as if led by temptation, and then... it hits me... WHY AM I HERE?! So, I flee for my life. That's like a horror narrative all on its own. So, that's looking pretty linear, then. I was just talking about what you've presently got out that I'm used to. Unfortunately, I haven't mastered time travel yet, so I can't tell you what you will make that is linear or not.
