I enjoyed playing your game! At first I was a little confused because I thought that the hint 'make sure you take longer' is from a misleading narrator :D
The static and dynamic blocks are well balanced (no overpowered block that made another obsolete) and the goal of taking long is more challenging than I originally thought.
Despite that I often had a glitch where two blocks sticked together when moving around. Sometimes I pressed 'play' and the last placed block was placed behind the play button.
