ELEVATOR HINT: build up a few elevators in one column (6 or 7), then start a new elevator on the same floor but one room over as the highest level of the first elevator. this way you have multiple elevator cars instead of just one trying cover 50 stories. this is what they use in actual high rises. +1 if you used this or found it helpful.
Controls could be better, takes a lot of practise to get through a couple of areas. Good story though, fun, challenging levels, amusing characters and sounds, but I won't pay money to play the rest.
I'll admit I jumped, so with that being said, the only thing keeping it from being a 5 for me was how short it was, and as was mentioned before, the ending could have been better.
You can drop number by big dot.
