Looks great. SoundFX's are nice as well :-)
I was expecting to tap left and right to change lanes rather than the car sliding around like it does. getting through the gates is easy enough, however tighter controls would make picking up the gold more fair. The challenge doesn't seem to be collecting gold, instead the challenge is keeping the car from oversteering and missing the gold which I don't think should be an aspect of gameplay.
The player should be rewarded for picking the correct lane to collect the gold and changing lanes at the right time to collect gold inbetween lanes... as it is, the player is penalised by being 1 pixel away from the gold's hitbox which is far to easy to do imo.
Other than controls, it's great fun and a nice take on the theme as well :-)
