I'll have to disagree as control's arent' very intuitive. It seems that they add artificial dificulty to the game.
Nice controls, graphics and music. For those who still don't get it, you've gotta go down the hole to deliver the first dudes, then park on the same spot you start the game. The following levels are all slight variations of the same thing.
Good game. Good controls. Needs a goal or objective or something.
Truly addicting. Sometimes figuring out what the objective is can be tough. But I keep coming back.
I like the design and thought of the game. The only issue I have is how the objective is unclear. I keep delivering the dudes to the other landing space, but nothing happens except for them getting dropped. I even landed successfully on the spot with passengers. Then what? Otherwise it's a great concept made well.
