Good game, small concerns

I think this game is very good, just small problems. If you tap a speed up, there is no screen asking something like "Are you sure you want to spend gems? Plus gems are limited, there should be like a mine or something that provides a gem every day or something.
Another thing, floors are not movable. I am not able to put certain floors with another like it. The last thing that is not as important, in the bowling alley, the first item you can make is just called "Ball" instead of bowling ball, which just bugs me a little. Anyways one of the best games Ive played.
