Thinking with Time Machine is amazing, using a time machine to solve puzzles. This new feature is just great to play, was fun to think what I should do at the same time but sadly these puzzles were not hard enough to keep me more than 30minutes in a room. It took time to do everything but the puzzles themself, were just easy. Simple story, go back in time to safe Glados from the two bots who you could play in Portal 2 Co-op.
The tutorial itself was really helpful, if I would had seen it first. I would rather mark the small video with something big so users can't miss the small video, like me. Sometimes the game crashed but this was not annoying much, just validated the game file and worked again. Well, it still looks like Portal 2 but the gameplay feels like a new game of Portal where you can only open on few spots a portal. Thinking with Time Machine was really fun, just was a bit short.
All in all a game for people who likes to puzzle and who owns Portal 2 of course.Puzzle - 4/10 (difficult of them all)
Gameplay - 7/10
Length - 2/10
Design - 8/10
Fun - 9/10 (there were some places which took me long to do)
