I like the art and the music, but i broke it twice or more times... On tutorial stage you can drop the block to the right and there is no way you can pick it again.
On the second stage of that tutorial the worker was carrying just air, but it does not allow me to drop or pick anything else.On the second stage i dropped a block on the roof in the left side block and it stayed there forever.
Anyway i enjoyed it so much :D
