Well... The concept is good enough. But id like to se some updates, maybe bigger planes and more passangers? You could add some more clues too, and storyline. If you still update the game, please do! Good luck :)
It's hard first... But i kinda got abit better at it (with the time ;) ) And the music was really great, it made me play it even longer! :D BUt i want more level's, more music? Better art (not that the art suck or anything :) ) Please make an O.S.S 2 with more of everything, maybe even alot bigger maps...
