Fun but short, and could have a bit more realism
It's a fun game, but actually quite short!
I agree with others that the elevators are a too large problem. The elevator blocks should at least have stairs included in them for customers who go a short distance or just prefer stairs, so that some of the complaints will stop. The elevator blocks could also be "3D", as in, have multiple shafts behind them.
The money amounts going in this game are also not very realistic. The price of playing a game of bowling seems to be higher than the price of staying at the hotel, and the price of building parts versus the price of services is way off.
For the rest, nice :)
