On the iOS (maybe android too) App Store there is a game called Portalize. Portalize is like Portal 2 and is free for iOS. The levels in Portalize are different from Portal 2. I am trying to make those levels for portal 2 the best I can. They are not the best cloned versions of the levels in portalise but I am trying. Also they problably wont be in order in the collection. Sorry. The puzzle solutions are the same though. And btw someone has done this before. They made them better than me (EDIT:Most of them. They all have the dual portal device so #3 and below are bacically more acurate than his.). I dont have links but If you want a good puzzle check out theres. Im bacically making this to kill boredom.
