The graphics are nice, the music is relaxing... I don't see how this is "future" related though? I agree with some of the other comments about the slow movement speed and no real clues as to which direction you need to go in to find coins (ie. no conveyance).
Suggestions for improvement would be to add acceleration and deceleration forces to player to make the movement feel more natural and fun, perhaps some signs to point you in the direction of coins, and maybe an exit that you can enter without the need to collect every coin (some players just want to progress faster than others).
