Very cool and distinctive art style, and the music choice adds a soothing atmosphere to the game. I would also like to comment on the great idea of adding names and little bits of story to why the building keeps growing. It really immerses you in the experience, and you sort of build a funny stor(e)y about why the building collapsed. It was a great addition to the gameplay.
For example, things have started going downhill for me because Steve kept wanting to add more pools! I almost reached 100K profits, and then Steve added one more pool...The rest is history.
The gameplay also suits the game quite nicely, and I found moving the blocks very intuitive.
Congrats on the game! It was a fun experience and a fun story!
EDIT: I sometimes pressed on the Pause button by accident, when the building blocks reached that height :)
