Love the art and atmosphere. But I think the controls are a tad poorly designed. There is no hotkey to check the customer book, and no hotkey to close any of the instruments other than a with the mouse. Additionally, the lift is hard to align (though I assume by design). I found dragging the lever using a mouse on the screen was more reliable than W/S throttle controls.
Anyway the art style and idea more than make up for it. Lost a bunch of times, absolutely enjoyed the passangers.
