"through time" is a level almost synonymous with the days when GD World was still a popular and relevant spin-off game. It's a cute level with a nice artstyle that serves as an admirable tribute and farewell to update 2.0, even in spite of its relatively short length. I also have to admit 'Promises' is a pretty good song. Overall, I think it's a very solid level and probably one of the best things to come out of GD World during its tiny lifespan of relevancy.
