A enjoyable little game you have here mate! Good job!
Love the little squishy detail that the car has when you hit the side or an obstacle. The music was a nice choice and i thought the sound effects for the menu buttons, gate opening pick ups and level completion were well implemented and tasteful.
One thing i would have liked is that when completing the level, i found it a little annoying that you were still going in the same direction as the previous levels. This may have been an intentional design choice, but i feel like for a game with a timer and potential for "speed running", would have been a nicer if you spawned in at a different starting rotation that fits the level. Just a thought.
Either way, very well done pal :)
