Great game, I had a lot of fun :)
I would have liked having a few more levels as this was quite quick to play through. As someone else also pointed out, an indicator to press E in the Zones would have been needed, I only found that out after looking at the comments.
A big compliment on your game mechanics, steering the car was really smooth and I enjoyed being able to not only be able to go in 4, but 8 directions. Well done!
