Thank you so much for playing and the kind words. I've been toying with the idea of having a "timed section" of a level later on in the game... and a possible leaderboard for the lowest total time to beat an entire world or get 100% in a world. The game currently does keep track of your time while your in a level (which you can view how long it took you to complete a level in the level select area of the main menu).
Great feedback! Thank you! 👍🏻
