Thanks for the feedback, th le game fits the theme by joining the levels together, first you play 1-1 than 1-2, and than you play 1-Joined which is the levels joined together.
The idea is that if you've seen 1-1 and 1-2 once you can do 1-Joined with less time, but due to time constraints I could not make the level generation distinctive enough that I could execute this effectively.
